wooden troughs well painted, lor the tiiculation ol hot water from a tin 

 boiler on the stove, running to the end opposite the flue. Two beds in 

 each division of the house, with walks between, gave six hundred and 

 forty square feet of effective surface for plant growth, and the heating 

 arrangements though so simple gave the very best results. The entire 

 cost was about two hundred and fifty dollars. The garden plants, except 

 celery, succeeded as well as the liest, but the market for su<;h as were for 

 sale was poor. Reference is again made to tiie rejiorts on Early Cab- 

 bage and Tomatoes. 



Arboretum — The Arboretum was begun, about thirty-five species of 

 forest trees tiaving been planted, and the land furtiier prepared for more 

 planting the coming season. 



Green-House — The University Green-house is now full of plants of 

 very many kinds noted for their beauty and u-ie. The ornamental grounds 

 received a large number of these plants for summer keeping, and togeth- 

 er with a rich display of annuals and other bedding plants, gave a scene 

 of beauty such as is seldom seen in public or private grounds. The 

 whole labor for the year on these grounds and in the green-house, was 

 done by the students under the supervision of the professor of Horti- 

 culture. Some interesting experiments have been tried with warm water 

 and cold water, with ammonia and with potash on pot plants, but are 

 to be repeated before giving results. The students of the Horticulture 

 class each root-grafted, and afterward planted with their own hands a 

 thousand or more apple cions, as practice in that special line of work. 



Horticulture at the University is beginning to attract more atten- 

 tion, as the plantations acquire age, and as the development of previous- 

 ly prepared plans shows the heretofore but partially observed work in 

 progress. T. J. Burrill. 



UNIVERSITY FOREST RECORD. 



Mr. Vickroy, orchardist for the Industrial University, has sent the 

 Secretary an accurate, tabulated record of the forest plantations connected 

 with the institution which, though valuable, is too elaborate and exten- 

 sive for publication here. 



The plantations made in eighteen seventy-one and eighteen seventy- 

 two consist of forty thousand eight hundred thirty-two trees (quite small) 

 planted on eight and a half acres. 



One and a quarter acres, only, were planted in eighteen seventy- 

 two. 



Of White Maples and White Elm there is one eighth acre each. 



Of Green Ash, Catalpa, Chestnut, Osage Orange, Austrian and 

 Scotch Pines, and Norway Spruce, each one quarter acre. 



Of White Pine, one acre. 



Of European Larch, two acres. 



Of White Ash, two and three-fourths acres.
