When the muriate of potash was used in the place of magnesia-potash-sulphate the 

 diameter growth of the trees and the total yield were considerably lessened notwith- 

 standing about equal quantities of actual potash were supplied in each instance. 



The varieties Baldwin, Gravenstein, Rhod< [sland Greening, and Roxbury Russet 

 were used in tin- experiment and showed considerable variation in their responsive- 

 ness to fertilizers. The variety Roxbury Russet made very nearly as g I growth 



where no fertilizer was used as w here barnyard manure was applied. Baldwin, on 

 the other hand, made a much more vigorous growth on the fertilized than on the 

 unfertilized section. 



A. considerable difference in the results is noted in the matter of quality of fruit 

 grown on the different sections. The best colored fruit was nearly always found on 

 the plat fertilized with wood ashes, followed by that on the plat which received 

 magnesia-potash-sulphate. The fruits <>n the unfertilized plal were firm, of good 



color and g 1 flavor, but were altogether too small and a very large proportion of 



them was unlit for sale. The fruit on the plat fertilized with barnyard manure was 



I rest of all except in point of size, [t was soft, rather poorly flavored, kept poorly, 



and was not well colored. 



The relation of soil texture to apple production, II. .1. Wildes {Science, n. 

 >./-.. .v i 1905 I, No. 570, />/>. 715-719). — The author discusses apple production as 

 related to soil texture, exposure, etc., the discussion being based on the results of 

 work done by the Bureau of Soils of the U. S. Department of Agriculture. 



Apple trees grown on a deep sandy soil, while they produce fruit of good quality 

 and color, are so short-lived as to make it inadvisable to plant orchards on this soil 

 except for home use. On the other hand, when the trees are grown on very heavy 

 clay soils, such as the Miami clay loam in Michigan, the Dunkirk clay in the Cham- 

 plain Valley, the Hagerstown (day in Adams County, I'a.. and on the Pikeville 

 area in Tennessee, the apples are inclined to have greasy skins and an inferior color. 

 The most successful commercial orchards are grown on loam soils between these two 

 extremes. 



Apple scions from bearing- trees— Influence of the stock i Rural New Yorh r, 

 64 (1905), Xo. 8907, p. 7/1). — In reply to a question as to the influence of selecting 

 scions from hearing trees for top-working purposes the opinions of G. T. Powell, F. A. 

 Waugh, F. W. Card, W. M. Munson, S. G. Maynard, and A. G. Gulley are given. 

 In general, this practice is believed advisable, though no definite experiments on the 

 subject are known to the writers.
