That tlio i)e:u'lK pliiiii. and fherry are more susceptiltle to injury 

 than the apple and ix'ar. 



That the injury varies with the variety, some being much more 

 susceptible to injury than others. 



That the leaves when young are less injured than when fully 

 developed, and those on Aveak trees more than those on vigorous, 

 healthy ones. Young leaves are covered with a natural bloom, 

 which wears off as they increase in size and their tissues become 

 more toughened. 



That Paris green cannot be used alone with safety stronger than 

 1 lb. to 350 gallons, but with lime mixtures it may be safely used 

 at the ifite of 1 lb. to from 100 to 25 gallons of water. 



That the foliage is most injured when kept constantly Avet by 

 light rains or foggy weather, Init that heavy rains lessen the 

 injury, the least harm being done in pleasant weather when the 

 liquid dries off most rapidly. 



That the time of da}' when the application of either insecti- 

 cides or fungicides is made is unimportant. 



The conclusions of this paper I have arrived at after a careful 

 sununary of the experiments made at the College and a careful study 

 of those of all of the stations of the countrj^ and I feel confident 

 that as soon as we master the details of the application of the two- 

 great remedies, Paris green and the copper solutions, so as to under- 

 stand the exact time to apply them and the quantity to use uudei' 

 var^'ing conditions, we shall be able to control the insects and fungi 

 attacking our fruits as well as we now control the " potato bug." 



Professor Maynard's essay was illustrated by many mounted 

 specimens of fungi which destroy fruit plants; also by several 

 forms of nozzles made for use in applying liquid fungicides and 

 insecticides to infected trees, shrubs, etc. The reading commanded 

 the close attention of a larger audience than had l)een present at 

 any preceding meeting this season. 



DiscrssiON. 



William D. Philbrick questioned the essayist concerning the 

 disease affecting the violet. 



Professor Mayuard replied that the violet disease is unques- 

 tionably of fungous origin ; that we often find masses of dust-like 

 spores upon d^'ing and dead leaves, but it cannot be determined 

 from this fact alone whether that fungus caused the disease which 

 destroyed the leaf. Mildews of this character generally develop 

 on decaying matter.
