A microscopical examination of tlie sections of new wood, combined with 
a chemical analysis of the food supply of the past season, stored for the 
production of foliage, would undoubtedly have revealed the secret. To my 
mind, however, nothing is clearer than that one of two things occurred; i. e., 
either the cellular structure was impaired by the untoward freezing, or the 
elaboration of the food supply was cut short from the same cause. Few such 
opportunities are afforded to place one’s finger on the exact time of serious 
injury, but this was one of such when the proof was absolute. Damage to 
trees is more often the result of an unpreparedness of the trees for sudden 
changes, rather than from the intensity of midwinter weather. 
I am convinced that excessive damage or total destruction of trees is more 
a matter of maturity than anything else. Well matured trees stand the test. 
Farther work will be done by us on these lines, substituting, perhaps, 
artificial cold for the genuine article, so that we may get at the proper com- 
binations.

MY THEORIES REGARDING PEACH CULTURE. 
BY R. MORRILL. BENTON HARBOR, MICH. 
First, The vitality of the young trees must be carefully guarded in the 
nursery and between the nursery and planter as a first class orchard cannot 
be growm from trees at all weakened by careless handling or exposure.
