shoots of the tomato resemble somewhat 

 the condition of the rose leaf in bronz- 

 ing, since they are more or less crowded 

 and stunted in appearance and obtain a 

 limited amount of nourishment. They 

 are of little or no account and add 

 nothing to the general welfare of the 

 plant, and in any system of pruning the 

 axillary suckers should be nipped out as 

 soon as they occur, and not allowed to 

 develop at the expense of the plant. 



The experiments in this series were 

 made for the purpose of testing the 

 effects of various methods of pruning 

 on the size and production of fruit, and 

 on crops grown during several years. 

 They were conducted in two different 

 types of greenhouses, both of which were 

 heated with hot water. One of these 

 houses had been devoted to lettuce and 

 "^ the other to crops of cucumbers. The 

 temperature, light and moisture condi- 

 tions in both houses were suitable for 

 tomatoes at any season of the year. The 

 cucumber house, which is designated 

 as No. I, is 24 ft. by 24 ft. and runs 

 east and west with the roof sloping 

 towards the south. It has five benches iS ft. long, 2J2 ft. wide 

 and I ft. deep, running east and west, each bench having an 

 elevation six inches higher than the one adjacent to it on the 

 south side. The glass in the lower part of the house is about 6 ft. 

 from the benches, and in the upper part about 8 ft. from them. 

 Each bench is furnished with a wire trellis upon which the plants 

 are trained. 



House No. 2 is an even span structure, 12 ft. by 40 ft., running 

 east and west with ground beds in the same direction. The 

 plants in this house were trained to sticks placed obliquely. 

 The plants on the south side in each house were the more favorably 

 situated with respect to light, but the experiments were so arranged
