DEPARTMENT REPORTS. 31 



GREENHOUSES. 



During the summer and early fall two additional houses were con- 

 structed to supplement the large range, one designed for roses being 19 

 feet wide and a carnation house with a width of 26 feet, the length of 

 both being 53 feet. The posts are of two-inch wrought iron and the gut- 

 1ers are also of iron of the Hippard pattern. The roofs are of cypress of 

 standard design, with 10 by 20-inch double strength glass. The rose house 

 is built with the long slope to the south, while the carnation house has its 

 long slope to the north, thus lessening the shade upon the roof of the 

 rose house. Jennings' patent fixtures were used for the benches and 

 purlins and in one house Evan's Challenge ventilating apparatus was 

 used while the Hippard Standard construction was used in the other. 

 The ventilating sash are hinged at the ridge in one house while in the 

 other the hinges are at the bottom of the sash. From this it will be seen 

 that in addition to their great value in the work of the department, the 

 houses serve as a means of illustrating and comparing the various methods 

 of greenhouse construction. 



In the rose house one bench was constructed of brick with a tile bottom, 

 but all of the others are ordinary wooden benches. 



Just north of the rose house and with a northern exposure, a leanto 

 propagating house, 23 by 7 feet, was erected. The building formerly used 

 us a stable was moved to the west end of the new houses and fitted up as 

 a workroom, for which it answers well. The work of constructing the 

 houses was done by Mr. Gunson and some of the students who are making 

 a specialty of horticulture. 



The grapery, Avhich was constructed some ten years ago from the better 

 portions of the old houses which were taken down at that time, needs 

 quite extensive repairs if it is to be kept in its present location, and from 

 the fact that it is proposed to heat the greenhouses with steam from the 

 central plant it is suggested that it will be better to take the grapery 

 down and use the cypress lumber and sash that is in the side-hill forcing 

 house for the construction of a greenhouse adjoining those built last year. 



INSTRUCTION.

 Botanical department in physiological botany. 



"The teaching in the winter term was as follows : Seniors to the number 

 of 20 received instruction in the evolution of garden plants. A course in
