THE PLAN BOOKS 
as full or as complete as he could have wished ; 
time was not given and money was not at 
hand to provide for the recording of all the 
interesting minor details. It must steadily 
be borne in mind that this great work has 
been carried on at a constant financial loss, 
and that every available cent of money has 
been required for the actual expenses of 
the tests themselves. Still, in addition to all 
the demands upon him, he has kept up these 
plan book records year in and year out, 
recording in them step by step the essential 
larger details of the life he has been molding. 
While they are curiously constructed, as 
unique as the man, they are definite, accurate, 
indisputable, scientific.—the most devoted 
adherent to scientific nomenclature could not 
have been more conscientiously accurate. 
Naturally, they were not made for the general 
public. They form a private record of the 
life history of the plants under test so pecu- 
liarly constructed, even though absolutely 
logical in their sequences, they would, in 
great part, be unintelligible without inter- 
pretation to any but the one who made them.
