oome data are given on a similar study of two widely different varieties 

 of Lima beans, the Henderson representing the tjrpe with small thin-walled 

 pods bearing small seeds, and the Burpee having comparatively large thick- 

 walled pods and large seeds. The seeds in the basal position were lightest 

 in all types of pods in both varieties, while those of the middle position of 

 3 and 4 ovuled pods were somewhat heavier than those at the tip. The 

 position giving the lightest seeds within a given type of pod yielded the 

 largest number of abortive ovules. No planting tests were conducted with 

 these seed. 



A test was conducted with 100 plants of the New Wonder bean with the 

 view of determining the relation of period of growth of plant to pods and 

 seeds. The percentage of pods having 1 or more ovules aborted was very 

 large and increased from the first to the last picking. Pods picked during 

 the midseason had the greatest number of seeds, and those picked during the 

 latter part of the season the lowest. The heaviest seeds were found in the 

 last picking and the lightest in the midseason picking. In 4-ovuled pods seed 

 weight gradually increased from the base to the tip of the pod. In pods with 

 more than 4 ovules seed weight appeared to be greatest near the middle of 

 the pod. Abortiveness was highest in the midseason pods and lowest in 

 those of the last picking. Within the type of pod the greatest percentage is 

 in the 3-ovuled pods and decreases with the Increase in the number of ovules 

 per pod. 



Some data are given on a study of the weight of tomatoes as related to 

 position in the cluster. With one exception the basal fruits were heaviest 

 and the terminal fruit lightest. 



A number of pea vines were examined to determine the relation between 

 the section of plant to the character of pod and seed. The results of the test, 

 as a whole, indicate that the first pods to form upon all vines of the Alaska 

 type had a larger number of ovules than those formed later. The middle 

 section of the plant produced the largest number of the pods and the heavie-st 

 seeds with far the lowest percentage of abortiveness. The abortiveness is 

 chiefly in the basal tip position of the pod. 



The breeding of vegetable fruits, E. J. Owen (Neic Jersey Stas. Rpt. 1917, 

 pp. 396-401). — In continuation of previous work (E. S. R., 39, p. 746) notes and 

 data are given on character transmission in bean, eggplant, muskmelon, and 

 tomato crosses. 



Spray and practice outline for fruit growers, H. J. Eustace and R. H. 

 Pettit {Michigan Sta. Spec. Bui. 93 {1919), pp. 32, figs. 6).— This bulletin con- 

 tains general directions for the spray treatment of various orchard and small 

 fruits and vegetables, including instructions for the preparation of sprays, dusts, 

 and other poisonous mixtures. 



Analyses of materials sold as insecticides and fungicides during 1918,

Sod, tillage, and fertilizers for the apple orchard. — A 10-year summary, 

 J. H. GouELEY {Neiv Hampshire Sta. Bui. 190 {1919), pp. 3-^0, figs. 6). — A 

 further contribution to the long-continued orchard management investigation 

 being conducted at the station (E. S. R., 38, p. 345), in which is presented a 

 10-year summary of the more practical results of various cultural and ferti- 

 lizer treatments, such as yield and growth of the trees and size of fruit in 

 the different plats. 



Trees growing in sod have not yielded sufficiently well to warrant the use 

 of the land for orcharding. They have made such inferior growth most seasons
