INTRODUCTION. 
In planning the programme for the meeting of the Association it was felt 
that no more appropriate subject could be chosen for consideration than 
that afforded by wheat, Winnipeg being now the focus point of a great 
area devoted to the growth of the cereal. Arrangements were therefore 
made in advance to hold a joint meeting of Sections B (Chemistry) and 
K (Botany) and of the Sub-section of Agriculture, for which communica- 
tions were invited from various gentlemen known to be specially conversant 
with the subject in one or other of its aspects. The discussion took place 
on August 30, the President of Section B being in the chair. The papers 
then presented are here printed, together with an abstract of that part of 
the address delivered by the President of the Agricultural Sub-section 
which dealt with wheat; abstracts of two papers dealing with economic 
issues, communicated by Professor Mavor and Professor Brigham, are also 
appended to the discussion. 
The civilised white man appears always to have enjoyed the use of 
wheat, no tradition being extant as to when it first became available. It 
holds a unique position among foods, being regarded as the staff of life; 
as other races of men have made acquaintance with it they have adopted it
