Foreword 
S INCE the first catalogue of vegetables for quick freezing was 
issued by us two years ago^ much progress has been made in 
tlie new industry both at home and abroad. Quick freezing of 
foods is now well past the trial stage and has become established 
as an important means of bringing the clioicest products of farm 
and field to our tables. 
Much further ex})erienee iias been gained in recent seasons as t,o 
the behavior of different varieties under the processes associated 
with quick freezing, and there are consequent changes in this 
catalog as compared with the previous edition. Only by repeated 
trial can the physiological changes of varieties be determined. 
Our listing is therefore narrower in some places; in others it has 
been expanded to include new varieties we have developed espe¬ 
cially for quick freezing. 
Good })rogress is being made in this regard, through the work eon- 
tinually carried on by our Research and Rreeding Department 
at the Asgrow grounds in different ])arts of the country, under 
fully qualified men. From time to time we expect to be able to 
announce additional developments thus acliieved. 
]\Iany problems still remain to be solved in connection with the 
adaptation of vegetables to quick freezing, but the care and deter¬ 
mination which Iiave already accomplished so much will undoubtedly 
attain to their solution.
