The latest spraying in the experimental orchards on Early Crawfordswas March 5th and 7th, a few days before the first blossoms appeared,but after the buds were beginning to burst. No trace of injury wasobserved. Some Fosters were sprayed on March 1st, and others onMarch 5th and 7th. On the latter date, one of the trees that was nearlyin full bloom, having a large number of fully opened flowers on it,was sprayed with especial pains and thoroughness, completely drench-ing it with the spraying material, in order to produce injury, if careful watch was kept of this tree, and the actual loss to it, so far ascould be made out, was eleven blossoms. The tree in question is four-teen years old, and had many hundreds of blossoms out when the. Fig. 6. Fruit from thinuing of Foster tree sprayed when in full bloom. spraying was done. So much fruit set on this tree that heavy thinning-out had to be done late in April, when 1,635 peaches were taken fromit, leaving still a good crop on the tree. (See Fig. 6.) A number of Susquehanna trees were sprayed on March 12th, 13th,and 14th, just when they were in full bloom; no apparent damagewas done to the flowers, and the fruit required very heavy thinning. Spraying was done on a number of the McDevitts on the 11th ofMarch, after some of the blossoms had fallen, and again no damagewas done. These experiments were practically duplicated in many differentorchards, and the same results were obtained in each case. It can thusbe safely said that late spraying with lime, salt and sulfur, under theconditions obtaining in Placer County, does not in any appreciable way 2—BuL
