Notes on Forest and Fruit Trees Growing on the Grounds of the 

 Agricultural College Fxperiment Station. 



BY E. S. RICHMAN. 



The material for this bulletin is taken from notes collected 

 during the last two years and from the present condition of the 

 trees. All the trees, except where otherwise stated, were planted 

 in the spring of 1890. 



The winters of 1890-91 and 1891-92 were not exceptionally 

 severe, the minimum temperature being 10 and 14 respectively 

 below zero, consequently they cannot be taken as conclusive J^. 

 determining the hardiness of the plants in question, while on the 

 other hand all plants suffering severely can safely be classed as not 

 hardy, unless some other cause than temperature can be given 

 for the injury sustained. 



The average growth in all cases was estimated by taking 

 measurements of a number (usually six) of the main branches 

 and taking their average length. The maximum growth is that 

 of the shoot making the greatest growth, it being usually the main 

 stem. The number of trees of each variety of forest or orna- 

 mental trees measured was in most cases six. 



Populus boleana. In i 890 the maximum growth was 3 ft. 

 9 in., and the average growth 2 ft. 2 in.; in 1891 the maximum 

 growth was 5 ft. 8 in., and the average growth 3 ft. 8 in. The 

 tree is clean and healthy and r akes a shapely but not a spreading
