THE ARBORETUM. 



This was started in 1873, and from time to time has been noticed in for- 

 mer reports. This spring a small piece on the south side, consisting of 

 about a third of an acre, was planted to white pines, Norway spruces and 

 box elders, alternating, the plants in rows four feet apart. The arboretum 

 is growing more and more interesting, and is a favorite place for many who 

 are interested in forestry. 



For most of the report regarding the experiments begun at the college, I 

 am indebted to my assistant, Eugene Davenport, who has shown great interest 

 in the subject and has proved himself an accurate and careful experimenter.
