When early in 1908 Bulletin 157 of the Maine Experiment Station was
published, it showed by averages as given in the table on page 202
that the egg yield at the station was for the entire period on the
decline. In Bulletin 157, the statement was made that "arithmetical
mistakes" and "faulty statistical methods" accounted for the
discrepancies between the former publications and the criticised
data. The further explanation that "the experiment was a success as
an experiment," etc., only appeared to the public mind as a graceful
way of explaining what was, to the practical man, an utter failure
of the entire work.
The unfortunate death of Professor Gowell, together with the fact
that he had equipped a private poultry farm with station stock,
added to the confusion, and the result of the bulletin was the
precipitation of a general "pow-wow" in which the poultry editors
were about equally divided between those who were casting
insinuations upon the personnel of the station, and those who
decried the whole effort toward improving the egg yield.
After going over the publications of Professor Gowell, visiting the
station and meeting the present force, I came to the following
conclusions regarding the matter:
Professor Gowell's work is open to severe criticism. Errors have
been made in conducting the work at Maine which have made it
possible for a mathematical biologist to take the data and seemingly
prove that selection, as practiced by Professor Gowell, actually
resulted in lowering inherent egg capacity of the strain of Plymouth
Rock hens under experimentation. Had Professor Gowell's successor
been a practical poultryman, it is my candid opinion that the public
would have been given a radically different explanation of the
results.
Professor Gowell is the author of the following statement: "The
small chicken grower is earnestly urged to use an incubator for
hatching." This opinion is not in accord with that of the majority
of breeders and the more progressive experiment station workers. The
opinion has been expressed by Professor Graham and others, that the
particular results at the Maine Station may have been due to the
decrease of vitality caused by continued artificial hatching. This
view may be wholly without foundation. Nevertheless, as the common
type of incubator is under heavy criticism, and it is pretty well
proven that chicks so hatched have not the vitality of naturally
hatched chicks, surely a series of breeding experiments would carry
more weight if the replenishing of the flock had been accomplished
by natural means.
