Part 3

The course in birds given by Professor Nininger was interesting and valuable. A number of new records for this region were obtained during the summer.

For the first time Miss Hills gave a course in drawing in connection with zoological subjects. This much-needed and valuable work will be continued during the coming summer, not only in a special course, but also in an optional way in connection with several of the other courses.

In connection with the ecology especially, more off-shore collecting was done than ever before. A number of longer trips were found interesting and valuable. Laguna at all times offers attractive walks and many short trips were taken by all classes. Some of these were for a few miles along the coast, back in the hills or by water or land for a considerable distance.

The rocks and coves were again explored, yet much remains unknown. Many new specimens to the locality were found, some of these were from deeper water, rare fish, large sea cucumbers, a large number of strange crabs and many other smaller but no less interesting creatures.

As in the past, a number of workers from other institutions used the private laboratories. The eight research rooms were in use most of the time by those doing more advanced work. It is expected that there will be a number of advanced workers from the northern and eastern universities during the coming season. For the first time the laboratory is provided with a satisfactory lighting system. Electricity is now established at Laguna Beach and the laboratory and tent city are well provided with an ample lighting system.

The tent city and dining hall will again offer accommodations at reasonable prices. The cost of tuition is $7.50 general charge and $3.00 an hour per hour taken. By an hour is meant the equivalent of an hour's work in a regular college semester. There are eight private rooms for special investigators.

For further information write to the Director, William A. Hilton, Pomona College, Claremont, Cal. (Laguna Beach, Cal., from June 26 to September 20.)

Courses Offered at the Summer School of the Laguna Beach Biological Laboratory 1917

To reach Laguna Beach from Los Angeles take the electric or Santa Fe to Santa Ana. From Santa Ana a morning stage leaves at ten, an afternoon stage at four.

Work begins June 27 and regular courses last six weeks, but the laboratory is open all summer.

No one may register for more than six hours. By an hour is included the equivalent of an hour's work during a regular college semester.

The staff of the Laguna Marine Laboratory for the summer will be as follows, several others from eastern institutions may be added later.

Pomona College

Located in one of the most healthful and beautiful parts of the west coast. The mountains reach an elevation of ten thousand feet within a few miles of the college and these with the nearby ocean afford many special advantages for the study of things not in books. Special advantages are afforded by the fact that the college limits its attendance, the freshman class being restricted to two hundred applicants. The success of the college is particularly indicated by the large proportion of the graduates who proceed to advanced work in the large universities. In addition, well-manned departments of music and art afford exceptional advantages.

Transcriber Note

The use of ligatures was standardized within each article. In the first article about Whip-Scorpions, the genus and species names were standardized to _Trithyreus pentapeltis_ Cook.
