Part 3
Every country boy lays up a supply of slippery elm bark to dry in the attic along with his nuts.
ASH TREES.
Ash trees are tall, straight, and handsome, with a very dark-colored bark, so regularly marked that one soon learns to know it at a glance. I once knew three of them that stood in an open pasture on the shore of Lake Ontario.
It was worth going to the pasture in a high wind to see the tall, beautiful trunks sway as the wind struck them. I used to wish I could climb up into the tops of them, though it would have been a very unsafe perch indeed.
You have guessed by now that ash trees have winged seed pods, and so they have.
When the little clusters of ash flowers first show in the springtime they are black, and the tree seems to have black-tipped branches. Soon the black tips develop into dark green fringes, though these are not airy and light, like the maple and elm fringes.
The best way for you to find out just how ash blossoms look is—but you know perfectly well what is the very best way to find out, and I hope you will take care to do it.
Ash seeds are winged like those of the maples and are called samaras, but they do not grow two together. Ash trees often bear great numbers of samaras, more than any other tree. Where ash trees grow near houses, the samaras often fall on the roofs and fill up the gutters, so that they have to be cleaned out, sometimes more than once in a season.
The wood of the ash is so very tough and elastic that from all time it has been used to make bows and spear shafts. Of course it is also valuable for less warlike uses.
When you read the “One Hoss Shay,” you will find one use to which ash wood is sometimes put.
The ash tree used to be held sacred by the ancient Norsemen, and some day you will read beautiful stories about the wonderful ash Ygdrasil.
The small tree we call “mountain ash” is not an ash at all, and it has, as you know, red berries instead of samaras.
PINES.
Pine trees bear cones, and cones do not fly. But if you examine the scales of the cones, you will find a winged seed under each. When the cones are ripe the scales open and the seeds drop out and are caught by the wind and floated away.
There are a great many species of pine trees. The seeds of some are large and sweet and are sold as pine nuts. These trees do not grow in this country, however, and we should have to go to South America, or to Asia, or western Europe to find pine trees from which we could gather nuts.
Squirrels gather nuts from all the pine trees, however, for they are not as particular as we, and think them all good. They are very clever at gathering cones, gnawing off the scales and getting out the seeds.
Pine trees, like the maples and elms, have two kinds of—not exactly flowers, but something answering to them. The ovules, or young seeds, are borne under the scales of the cones, and the stamens are in catkins. Sometimes these catkins are very large, and they bear a great deal of pollen which the wind carries to the cones.
A pine forest is always a sweet and delightful place. When the sun shines on the trees they fill the air with fragrance.
Pine trees used to grow all over the northern part of the United States, but they make very valuable timber, and so have been carelessly cut down and the forests destroyed, until now in many places there are almost no pine trees left.
This was a great mistake, as the people now know. The white pine of the North gave a soft white wood that could be easily carved or “turned,” and it was used more extensively than any other wood as long as the forests lasted.
A large part of the South is still covered by forests of yellow pine, whose wood is dark, hard, and valuable for building purposes.
The pine forests of the South also yield large quantities of tar, resin, and turpentine, and it is sad to see the forests being carelessly destroyed each year. The trees are cut for their sap, from which turpentine and other products are made, but if the same trees are cut three years in succession they die.
The turpentine makers, however, cut them as long as they will yield sap, because it is easier to stay in one place three years than to move their camps to a region of fresh trees. This is wrong, and will result in destroying the valuable Southern pine forests in a short time.
We should take care of the trees, for they are our good friends. Besides providing wood for all sorts of uses, they protect the earth, keep it moist, and prevent the streams from drying up. In many places the farming land has been destroyed, because the forests were cut down when the land all about dried up, so that nothing of value to man could grow on it.
With proper management trees can be cut for use without destroying the forests.
SEEDS THAT FLY WITHOUT WINGS OR PLUMES.
Poppy seeds have no wings and no plumes, and yet they are carried far and wide by the wind. That is because they are so very small and so very light. They look more like dust than seeds.
The poppy pod is like a cup with a cover on, but around the edge, just below the cover, is a row of small holes, each covered by a lid. These lids do not open until the poppy seeds are ripe; then they do, and the fine seeds can get out of the holes. But _how_ do they get out? They cannot move of themselves, but the wind sways the poppy pod this way and that on its long stalk, and the little seeds are shaken out only to be caught by the wind and blown away.
Perhaps you think that is not a very sure way for the seeds to escape, but if you examine a poppy head that has been ripe for some time you will find scarcely a seed in it, so it proves to be a better way than it looks.
Nature’s way is generally the best way to accomplish an object.
Poppies are often seen growing by the roadside or in the garden, far from the flower beds; that is because the wind has blown the seeds to these places.
In England the wheat fields are often gay with scarlet poppies, which have, no doubt, been sown with the wheat. They are beautiful to look at, though the farmer does not enjoy seeing them in his wheat.
Opium is obtained from the juice of the partly ripened seed pods of some kinds of poppies. Opium is very valuable as a medicine, but it has to be used with great care, as it is also a powerful poison.
A valuable oil is expressed from the seeds of the opium poppy. This oil is used for illuminating purposes in some parts of the world, and also for soap-making. The finer quality is used as food, instead of olive oil, in countries where oil is eaten instead of butter, and it is also used in grinding artists’ colors.
OTHER SEEDS THAT ARE MOVED BY THE WIND.
Many, many other plants have seeds or seed pods that can be carried away by the wind. The fields and hedges are full of plumes and winged seeds, and of seeds so light as to be readily carried away without special plumes or wings.
At the top of this page is the picture of a trumpet vine. When you have the chance, examine the seeds in the pod of the trumpet vine and see how they are enabled to fly away.
Hops are pretty plants, and useful ones as well, and if you examine hop seeds—you will see—what you will see!
Some clovers have seeds that fly. See if you can find them.
Linden trees are covered with clusters of white sweet-scented flowers in the early summer. Each cluster of flowers is attached in a curious way to a wing, and often the whole cluster, with its wing, falls together and is blown to some distance by the wind. When the lindens are in bloom you will know it by the humming of the bees, for they are very fond of linden honey, and the trees often sound like an enormous beehive, there are so many bees about them.
It would take altogether too long to tell about all the seeds that are carried by the wind, but you can find a great many of them without being told; and that, after all, is the best way. At the bottom of this page are the seed pods of the cow parsnip, a very large, coarse, but rather handsome weed, often found in the corners of pastures. You can see that its seed pods fly.
TUMBLEWEEDS.
Tumbleweeds _are_ funny! They do not fly in the air, but they go scurrying over the surface of the earth. They grow on the Western plains and in other places, and sometimes get to be as large as a bushel basket.
They are not very interesting until they begin to tumble. This happens in the fall of the year.
The plants grow like ordinary little bushes in the summer and bear a great many clusters of small flowers. Late in the season the leaves fall off, and the stems of the plant curl over and make a ball of it. The seeds do not fall yet; they can be seen in pretty brown clusters inside the ball.
Along comes a gust of wind; the tumbleweed, all rolled up and quite dry now, breaks loose from the earth and away it goes, head over heels, rolling like a wild thing across the prairies.
It is very funny to see a prairie full of tumbleweeds racing along. They look as if they were playing tag. When a train passes, those near the track are caught in the draught and off they start, head over heels, as fast as they can. They look exactly as if they were chasing the train.
The tumbleweed does not send its seed children out alone into the world; it goes along and spills them over the prairies, as it tumbles about; for, after a while, the seeds get thoroughly ripe and fall off. If you were to see the tumbleweeds rolling about over the prairies in the fall, you would not wonder there are so many of them growing everywhere in the summer.
There are several kinds of tumbleweeds in the West. One of them is called the Russian thistle, though it is not a thistle. It came from Europe and has proved to be the very worst weed the farmer has to deal with.
It tumbles about in the fall, rolling far and wide over the prairies before the high winds. In a few years it has become such a nuisance that large sums of money are spent by the government to exterminate it. In some places the school children have been taught to recognize it and to pull it up wherever they see it growing.
WANDERERS THAT CLING
BURDOCKS.
Seeds have other ways of going about besides being blown by the wind. One way is to fasten on to anything or anybody that passes and get carried to some other place.
Burdocks do this. Burdocks grow in dooryards if they get a chance, and in fence corners and pastures and along roadsides, and in fact almost anywhere. They are sturdy weeds and often grow quite large. In “The Ugly Duckling,” Hans Andersen tells us about them.
“In a sunny spot stood a pleasant old farmhouse, circled all about with deep canals; and from the walls down to the water’s edge grew great burdocks, so high that under the tallest of them a little child might stand upright.”
Like the dandelions and Canada thistles, the burdocks came from Europe, and a great many people wish they had stayed at home. That is because of their burrs, which are a nuisance in the fall of the year.
Everybody knows what burrs are. They stick fast to the clothes of people and get on the tails and manes of horses, where they must cause a great deal of discomfort, and where it is a great deal of work to pick them out. They get upon the tails of cows, too, and the fleeces of sheep, and dogs get them on their ears. The reason is this: the burrs are full of seed pods. The burdock flower head is, like the dandelion, made up of a great many tiny flowers, and each flower has a close-fitting pod containing one seed, or an akene, as we have learned to call it.
The head of flowers is covered by stiff green bracts, and at the end of each bract is a hook. These hooks are soft when the flowers are in blossom, and they do not catch fast to things. But when the seeds ripen, the bracts grow hard and stiff, and so do the hooks at the end.
Now, when an animal or a person comes along and brushes against these ripe burrs, the strong hooks catch; the burr, full of ripe akenes, is pulled from the plant and is carried away. It is easy to guess why this happens.
When one tries to pull a ripe burr from the clothes, it falls all to pieces and the akenes spill out. Then each hook has to be pulled out separately, and very likely each one will prick the fingers.
Children sometimes pick the burrs before they are ripe, and stick them together to make baskets and other things. Then the burrs do not fall to pieces nor prick the fingers much. The burdock has a rank, disagreeable odor that clings to the fingers a long time after the burrs have been handled. It is not easy even to wash it off.
Children often pick ripe burrs and throw them at each other. Some think this is funny, and some think it is naughty.
Burdocks yield a valuable medicine; so they are useful as well as troublesome.
COCKLEBURS AND SAND SPURS.
Cockleburs are covered with hooks, too, but they are much uglier than burdocks, for their seed pods are very hard and are covered on the outside with stiff, strong hooks that prick like needles.
When one walks among cockleburs, he soon stops to pick them off, for they hurt so, he cannot bear it.
Sand spurs are even worse than cockleburs. They are the seed coverings to a kind of grass.
In Florida this grass grows in tufts and spreads out close to the ground. Some of its stalks are covered with sand spurs that, like the cockleburs, are hard and are covered, not with hooks, but with very hard spines. These spines stick out in all directions and readily fasten upon whomever or whatever comes along, when they leave the parent grass and are carried away. After a time they are picked off and thrown on the ground, or they fall off, and that is their way of traveling to find a place to grow.
Dogs often get them in their feet, and then they have a hard time picking them out, for of course the poor things cannot walk with sand spurs between their toes.
There was once a dog that hated sand spurs and loved people so much that when any one came near him with sand spurs on his clothes, he would at once begin to pick them off, and the expression with which he jerked them out of his mouth showed very plainly what he thought of sand spurs.
TICK TREFOIL.
When walking in the woods in the late summer we sometimes find queer jointed little pods, like unfinished pea pods, clinging to our clothes.
These come from plants that belong to the Pea family and are called Tick Trefoil. There are nearly two dozen kinds of them, and sometimes they seem to be everywhere in the woods and thickets.
The pods are like pea pods, only that they are jointed, and the joints break apart, so that each may be carried away separately. Each joint contains a little pealike seed.
The outside of the pod seems fuzzy, and it clings very closely to whatever it touches. If we look at the fuzz with a magnifying glass, we shall find it made up of innumerable little hooks.
The hairs that cover the pod are turned up at the end to form little hooks, very delicate, but able, when there are so many of them, to hold on very tightly.
They seem to snuggle down into the cloth they touch, so that it is difficult to pick them off, and the joints all separate when we try to remove them, so that each one has to be taken off separately.
Another plant whose seed pods are covered with hooked hairs is the sweet-scented bedstraw. This is a pretty little plant that spreads about on the ground. Its flowers are small and greenish, but the whole plant when in bloom has a pretty lace-like effect as we find it in the woods very often growing about fallen logs.
Its seed pods are small and, like the tick trefoil, are covered with hairs that, under the magnifying glass, are seen to be hooked.
The enchanter’s nightshade is another little plant whose seed pods are covered with hooked hair. It is as pretty as its name and is to be found in damp woods.
There is a tall leafy kind that grows sometimes two feet high and is topped with numerous branches of small white flowers. As the flower stem lengthens, the flowers continue to unfold at the tip, while lower down are the many little seed pods, shaped like little tennis racquets.
The prettiest enchanter’s nightshade, however, is a little fairy that sometimes grows on decaying logs. It is often not more than three or four inches high and ends in a branch of pretty little white flowers with bright red calyx lobes. After these dainty blossoms come the little hook-haired, racquet-shaped seed pods.
Look for enchanter’s nightshade the next time you go to the woods in the summer time. Below is a picture of the large one.
STICK-TIGHTS.
Stick-tights are troublesome to us, and we call them very disagreeable names, such as beggar ticks and beggar lice. But they are really not bad at all and are quite pretty. If they stick to us, that is our fault quite as much as theirs, for we should keep away from them if we are unwilling to carry them about.
They cling to whatever comes along, because that is their way of traveling about. They cannot walk or creep or crawl or jump; neither can they fly very far nor move in any other way, excepting as they are carried.
You know how they look—so [Illustration: Stick-tight plant.] Of course this little brown, flat object with horns is an akene. Inside it is a seed. The two horns at the top are able to fasten it quite tightly to a woolen dress or a sheep’s fleece. If you look carefully, you will see little hard teeth on the edge of the stick-tight that help it to cling. On one species of stick-tight these teeth point backward, like the barbs of a fishhook, and that kind sticks very tightly.
Stick-tight plants blossom in the summer time. The greenish-yellow flowers are clustered in heads like the dandelion flowers, and like those each stick-tight flower has an akene at the bottom. These akenes grow much larger than those of the dandelion, and they have the two horns on their heads.
The akenes stand on a flat cushion, just as the dandelion akenes do, but these do not wait for the wind to blow them away, though, if nothing comes along to pull them loose, they in time become very dry and fall out, and then the wind often carries the light little things some distance.
But their favorite method of traveling is by stagecoach, and if you happen along at the right time they will take you for their stagecoach, and let you carry them to a new place. Sometimes the plants grow so closely together that in passing through them one becomes quite covered with the little brown things, and it is a long and tiresome task to pick them out.
They, too, get on the tails and manes of horses, and the tails of cows, the coats of dogs, and the fleeces of sheep; but they are not nearly as troublesome to these creatures as are the burdocks.
There are several species of stick-tights, or beggar ticks, as they are more generally called.
Some have rather large flower heads, with the outer flowers each provided with a long, broad yellow petal. These are often called wild sunflowers, because they look something like a little sunflower.
There is a plant called Spanish needles, very closely related to the stick-tights, and that has four horns to its seed pod.
The burr marigold, which grows in wet places, and whose greenish flower heads are round like a marble, is also related to the stick-tights, and, like the Spanish needles, has four horns.
A great many plants have these little horned seed cases, and when you go about the country in the fall of the year you will be certain to make the acquaintance of some of them. The plants with horned seed pods wish their seeds to get out of the dense thickets in which they usually grow, and they do what they can to help them.
AGRIMONY AND OTHER WEEDS.
In the fall of the year and towards the end of summer we find a great many weeds in the woods and along the roads, sending their seeds out into the world by means of stout hooks, or else hooked hairs or sharp spines.
The agrimony is one of these. It is a common, rather pretty plant with yellow flowers, and it has a burr or seed pod, armed with hooked prickles around the waist, so to speak.
After a walk in the country through woods and fields, in the autumn, one will be likely to find a number of little things clinging to one’s clothes. Instead of merely shaking or picking them off and throwing them away, carefully collect them, and when there is time look at them.
You will very likely find yourself decorated with a number of different kinds of seeds or seed pods, that vainly hoped in you to find a means of traveling to new and better places of growth.
All these little brown things are disappointed, or would be if they could feel disappointed. But you can profit by their misfortune, and, by carefully examining the little wanderers, can learn a great many interesting and wonderful truths about the plant world in its effort to scatter its seeds.
FLAX.
The flax is a very useful plant, for the fibers of its stems are long and strong, and are spun into thread and then woven into linen.
Besides this, the seeds are useful. They contain an oil which is pressed out and is known as linseed oil. It is used a great deal by painters in mixing their paints.
When flaxseeds are wet they become very sticky on the outside. A jelly-like substance covers them, and this it is which we drink in “flaxseed tea” to cure our colds.
You can easily see this jelly-like covering by putting a few flaxseeds in a few drops of water and leaving them there a little while.
You can readily see that when the flaxseeds are shed in the field and are met by the rain, they would stick to the feathers, feet, and beaks of birds that came to eat the seeds. If the birds flew to another place, as they often would, to clean their plumage, they would rub off the flaxseeds, that mean-time had become dry again, and often the seeds would drop off, as the bird moved about. In this way they would get planted in new places. No doubt the sticky covering to the wet seed also helps to anchor it to the ground and keep it from blowing away when once it has settled down on the earth.
The flax plant that we find so useful is not wild. It is carefully cultivated in many parts of the world and has been cultivated for so long a time, and in so many places, that nobody knows where it first came from. It is a pretty plant, that bears bright blue flowers.
Why do you not buy a penny’s worth of flaxseeds at the drug store and plant them in your garden and become acquainted with this very interesting and beautiful little plant?
MISTLETOE.
The mistletoe grows on trees. It has no roots of its own, but attaches itself to the bark of the tree and sucks out the sap.
Since it lives up in trees, its seeds must be able to find lodgment in these high places; and this the birds help them to do. The mistletoe has light green leaves; it grows in bunches and bears white berries.
The seeds in the berries are covered by a viscid substance, and when the birds eat the berries, some of these seeds will be apt to cling to them and be left on the branches of some other tree.
If the seeds happen to get swallowed, that does not hurt them, for they are not digested, but are passed out just as they were swallowed, and they then often fall upon the tree branches, where they can grow.
