diameter and 18 in. high. These are hung on and connected with a 5-in. hol- 

 low, stationary iron axle. Vertical suction pipes descend from the axle in each 

 wheel. The engine and pump are carried on a platform between the wheels 

 and connected with the axle. Among the advantages attributed to this ma- 

 chine are its low center of gravity; wide tires; relative lightness as compared 

 with machines now in use; power for agitation supplied by the horses, thereby 

 reducing the necessary engine power; and its short construction, making it easy 

 to turn in the orchard. 



Some investigations in grafting, N. O. Booth {Proc. Soc. Hort. ScL, 10 

 (1913), pp. lJfJf-H9). — ^A discussion of the various factors which tend to restrict 

 (he art of grafting. 



Characteristics of one hundred seedlings of the Northern Spy apple, 

 W. T. Macoun {Proc. Soc. Horl. Scl, 10 {1913), pp. 76-85).— Data are given 

 showing the similarity or dissimilarity as to various characteristics between 100 

 Northern Spy seedlings and the Northern Spy parent. Briefly summarized. 35 

 per cent of the seedlings resembled the Northern Spy in general apearance, 12 

 per cent in form, 39 per cent in flesh, 19 per cent in color, and 35 per cent in 

 flavor, and 28 per cent showed no marked resemblance. The Northern Spy, 

 which is late in coming into bearing, has given this characteristic to most of 

 the seedlings. 



The author concludes that the Northern Spy is one of the best pai'ents to 

 use in crossbreeding, since it has impressed its good characteristics on a large 

 proportion of its iirogeny, although a self-sterile or partly self-sterile variety. 



The effect of pollen of Wagener and Mcintosh on the size of and number 

 of seeds in Wealthy apples, J. W. Crow {Proc. Soc. Hort. Sci., 10 (1913), pp. 

 153-155). — The author used pollen of the Wagener and of the Mcintosh apples 

 in fertilizing flowers of the Wealthy apple. 



The data secured indicate that Mcintosh pollen is more effective in produc- 

 ing a set of fruit on Wealthy than is the Wagener pollen. The resulting fruit 

 is likewise n)ore abundant in proportion to the number of blossoms polleuized, 

 and the average size of the fruits is larger. On the other hand, the average 

 number of good seeds per fruit was greater for the Wagener pollen in spite 

 of the fact that the average number of seeds which had undergone at least 

 partial development was approximately the same in both cases. It appears 

 that the Mcintosh pollen may have some effect on fruit setting and the size of 

 fruit entirely separate and distinct from its effect in bringing about actual 

 fertilization. 



Some peculiarities of native Georgia apples, T. H. McHatton (Proc. Soc. 

 Hort. Sci., 10 {1913), pp. 67-70). — The author here calls attention to a peculiar 

 type of basin, calyx, and calyx tube observed in a large number of varieties of 

 apples grown in the mountains of northern Georgia. The calyx tube is found 

 to be very broad and deep and somewhat between urn and cone shaped. The 

 lobes appear to have fallen away, leaving a very broad and open space at 

 the bottom of the basin. The apples also have a marked oblate shape. 



Factors which determine color and size of peaches, M. A. Blake {Proc. 

 Soc. Hort. Sci., 10 {1913), pp. 83-S8). — A general discussion relative to the 

 various factors inliueucing color and size of peaches. 



Effect of pollination on the fruit of Diospyros kaki, H. H. Hume {Proc. 

 Soc. Hort. Sci., 10 {1913), pp. 88-93). — The author's observations relative to 

 the fruiting habits of the Japanese persimmon lead him to conclude that the 

 fruits of D. kaki of the same variety and on the same tree often vary greatly 

 in size, shape, color of flesh, quality, taste, and time of ripening. The under- 

 lying cause of these variations is attributed largely to the pollination factor. 

 All varieties of Japanese persimmons thus far studied are light-fleshed when
