It feeds prin- cipally upon the leaves, occasionally attacking the fruit, and may be detected by the faded out, pallid appearance of the foliage, dotted here and there with little black specks of excreta. Figure 6 shows two peach leaves which have been attacked and two which are normal from the same tree, and gives a good idea of their appearance after this pest has been feeding upon them. Experiments show that tobacco prepa- rations are of little value in controlling this mite; that they will kill the mites, but not the eggs. As the latter are almost always present on a tree where the mites are feeding such sprays can only be efTective when repeated applica- tions are made. The sulphur spray was again tested this season, this time at Palisade, Colorado. Some badly infested pear trees were treated, using ten pounds of sulphur to fifty gallons of water. Results of this test were perfect, and a week after the trees had been sprayed it was hard to find a living mite on them. An interesting point in connection with the sulphur treatment for brown mite is: The adult mites are not immediately affected by the spray, but those newly hatched die shortly after the application. An examination of a tree the day after spraying with sulphur is usually disap- pointing, for the adult mites may be alive and abundant. In all the tests made a very few newly hatched, six-legged mites have been found twenty-four hours after spraying, and in a week's time neither adult nor newly hatched mites can be found. The sulphur adhering to the bark and leaves undoubtedly kills the young mites as they hatch from the eggs. Whether the older ones are killed by the sulphur or simply die a na
