This Shafting is in every particular superior to any turned Shafting ever made. It is the most ECONOMICAL SHAFTING to buy, being so very much stronger than turned Shafting.

_THE REASONS WHY_

DOOLEY'S YEAST POWDER is preferred to any other Baking Powder in market, are owing to its perfect purity, quality, quantity, and economy. The ingredients are strictly free from deleterious substances, and hence the full strength of each is obtained, and the results are uniform every time it is used. This cannot be the case in those of ordinary manufacture, and for proof of our assertion, we ask those who have never used DOOLEY'S YEAST POWDER to give it a trial. Your grocer keeps it.
