Department of Horticulture and Forestry
Since publishing Forestry Bulletin No. 32 a very severe test of the hardiness of the several species in the forest plat at this station has been passed through. 1893 was perhaps an average season with something less than the usual amount of rainfall, but the season of 1894 was almost unprecedented for the extreme duration of the dry period. It began early and continued until after the plants had completed their season's growth. For some species under such trying conditions the provisions for winter appear to have been insufficient, as is evidenced by the great falling off in number in some of the plats noted further on in this bulletin. Severe drouth [sic], however, was not the olJ.ly cause of the loss of vitality. On May 19, 1894 and again on May 10, 1895, this section was visited by severe frosts which destroyed tender plants and nearly all the fruit. Some of the forest trees are susceptible to injury from late frosts, the tender varieties were set back both seasons and as a result made a low average growth. Certain varieties had made more growth previous to the frost of May 19th than was made during the remainder of the season. It, therefore, stands us in band to select both for grove and street planting those varieties which show the greatest immunity to late spring frosts.
