barrels, although the crop is not completely harvested at date of writing. 

 Accurate accounts from each tree have been kept, giving yield, weight of 

 apples per bushel, nni\ grade of fruit, as previously. 



Plant Breeding Projects. 



The experiments in breeding of squashes and muskmelons have been con- 

 tinued and are practically finished. Complete sets of data have been obtained 

 as results of these studies. Photographic records showing the various varying 

 proportions in form and color throughout the succeeding generations of hybrids 

 have been made. 



REPORT OF WORK IN THE GREENHOUSES. 



The work in this department has been conducted on a semi-commercial 

 basis, i. e., we have endeavored to do as much business as possible commercially 

 in order that the greenhouses may be as nearly as possible self-supporting. 

 We have not, however, overlooked the importance of the value of the green- 

 houses being used as part of our laboratory. No. 1 house has been utilized 

 entirely as a laboratory in connection with our teaching work. No. 2 house 

 we have used solely as a vegetable forcing house, the following crops being 

 grown: lettuce, tomatoes, and cucumbers. We have conducted some work 

 on the following fines of investigation: A variety test of lettuce under glass, 

 also several crosses on tomatoes have been made, and the hybrids grown with 

 a view to produce varieties which are in some measure improvements over the 

 old ones. 



No. 3 house has been used during the last two years exclusively by the Botan- 

 ist. No. 4 house has been used as a lettuce house during the winter months, 

 followed by cucumbers during the early spring, the cucumbers being followed 

 by potted plants. The work and investigation now carried on with the cucum- 

 ber (which is a hybrid bred by the Department of Horticulture, New Hamp- 

 shire College) is to develop a better form in the fruit, particularly the shoulder 

 which has a slight tendency to taper. No. 5 and No. 6 houses have been 

 devoted to carnation growing and breeding work during the winter months, 

 followed by melons which have been grown and many crosses made on which 

 the studies in Inheritance of Characters are being made. 



No. 7 or palm house is devoted entirely to palms, ferns and exotic plants, 

 these plants being used for decoration at our social functions, and exhibited in 

 various places as part of the College exhibit.
