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 successful 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.
