FORESTRY. 



J. C. WRITTEN. 



During the season of 1892 no new plantings have been 

 added to the forest plats. The season has, as a whole, been 

 favorable to tree growth, though so wet as to prevent the suc- 

 cessful extermination of weeds. During the early part of the 

 growing season, copious rains greatly hindered work with the 

 cultivator, and also kept the, ground so cold that weed growth 

 did not begin in earnest until the latter part of June. About 

 this time the soil became dry enough to be worked to better 

 advantage, and a vigorous use of the cultivator was continued 

 until July 7th, when cultivation ceased, in order to allow a 

 thorough ripening of the new wood, as well as to allow the weed 

 growth to cover the soil for holding the snows of the coming 

 winter. Weed growth continued very late, so that clipping 

 with a scythe became necessary, in some plats, where too great 

 a tendency to ripen foul seed was noticed. This has been the 

 only season in the history of the forest tree plantations at this 

 Station, that has afforded opportunity to note the comparative 

 effects upon different varieties of copious rains throughout the 

 entire growing season. This adds features of interest that have 

 not before been noted. Heretofore observations have been made 

 principally with a view to determining what trees will quickly 

 form leaf canopy, and thus prevent weed growth. Some of the 

 plats have already reached that stage and will no longer admit 

 of cultivation. 



The accompanying diagram represents the entire forest 

 plantation, with the exception of a seedling plat, and gives the 

 varieties of trees in each plat. Plats 1 to 10 were planted in 

 1889; plats 11 to 22 in 1890 and plats 23 to 30 in 1891.
