Report of the Horticulturist of the 



Temperature of the lioiisc during the winter. — The range of tem- 

 perature for the house during the winter is indicated by the fol- 

 lowing table which shows the daily temperature at the east and 

 west ends of the house taken at 7 a. m., 12 m. and G p. m. The 

 records are averaged by weeks from September 28, 1895 to March 

 14, 189G, a period of twenty-four weeks. In twelve cases, or just 

 half the time, the weekly average for 7 a. m. at the west end was 

 slightly higher than at the east end, the difference varying from 

 0.13° to 2.00°. The weekly average at the east end at noon was 

 higher than at the west end in ten cases, and one week the noon 

 average was the same for both ends of the house. The weekly 

 average for C \}. m. was higher at the west than at the east end 

 in but seven instances. From November 22 to February 8 the 

 6 p. m. average was uniformly lower at the west end. This may 

 be accounted for by the fact that during the short daj's of winter 

 the head greenhouse, into which the west end of the tomato 

 house opens, cuts off the sunlight from that end of the house 

 during the latter part of the afternoon.
