The lime-sulphur was a fresh sahiple of a commercial concen- trate, having a density of 34° Baume. This was used at the strength recom- mended upon the container for dormant applications, one to eight. Two propri- etary miscible oils were tested, these being diluted one to fifteen, the usual dormant season strength. Although both samples were fresh from the man- ufacturers, one was evidently imper- fect as there was some free oil present. In the tests, however, this imperfect sample showed to less advantage in de- stroying the eggs than the well-pre- pared sample, a rather unexpected out- come, perhaps, in view of the presence of free oil. These tests, as in the case of those following in which the aim was to determine the comparative kill- ing efficiency, were carried out in the laboratory, where careful counts could BETTER FRUIT Page 2Q Orchard For Sale At Grants Pass, Oregon 2S0-acre ranch, about 60 acres young orchard, mostly pears, just coming into bearing.
