To quickly assess the difficulty of the text, read a short excerpt:
No effort was made to communicate with yeast manufacturers or to interest them in the fact that the experi- 6 Poultry Bulletin ment was contemplated. Fleischmann's Pure Dry Feed Yeast was chosen as a source of yeast supply. First — because of its wide distribution and availability. Second — it was chosen because of the fact that it was a pure yeast product carrying no adulterants and containing no carrying agent. Third — it was chosen because of the fact that it was a live yeast in that when su...bjected to proper conditions of moisture and temperature the yeast started to grow and multiply just as normal live yeast will do. Lastly — the Fleischmann product was chosen because being in a dry state it was easy to store and handle. Six hundred forty hens were used in the early 1924 test. They were all yearling hens which had laid heavily the previous year and which had been through an extended moult and had come back into normal produc- tion about the middle of January. They were all Single Comb White Leghorns.
