ling of the fruit occupies most of the bulletin. Tests showed that apples 

 which are to be held for a long period should be stored at 32° F. Mcintosh 

 apples develop better flavor if the temperature is held at 45° at the time 

 of harvest and reduced to 32° by the third week after picking, but this 

 higher temperature should not be used if the apples are to be held 

 later than January 1. 



361 Control of Tomato Leaf Mold in Greenhouses. By E. F. Guba. 36 pp. 

 April 1939. 



The successful control of the disease involves cultural practices, green- 

 house management, greenhouse location and design, and the use of chem- 

 icals for the disinfestation of the greenhouse interior and the protection 

 of the plants from infection. All these factors are discussed and rec- 

 ommendations based on experimental results are made. 



362 Haying in the Rain: A Study of Gra^s Silage. By J. G. Archibald and C. H. 

 Parsons. 19 pp. April 1939. 



Unlike corn, grass and legumes require the addition of a preservative 

 at the time the silo is filled in order to make satisfactory silage. At present 

 molasses seems most satisfactory for this purpose from the standpoint of 

 both economy and results, although phosphoric acid may be used. De- 

 tailed directions are given for ensiling grass and legumes, using molasses. 

 Feeding trials showed that the molasses-grass silage was about equal to 

 corn silage and somewhat superior to dry hay, although it probably should 

 not entirely replace hay in the ration. It diff'ers only slightly from hay 

 in cost and is generally less expensive than corn silage. 



363 Milk Cartage in the Southwick-Agawam Area of the Springfield Milk Shed. 

 By Alfred A. Brown and J. Elizabeth Donley. 26 pp. May 1939. 



Analysis of this section of the Springfield milkshed showed that the 

 present type of service under a variety of rates has provided producers 

 with adequate transportation, but the cost has been high, largely because 

 of excessive mileage, light loads, extreme variation in load size, unused 

 truck capacity, and the like. Two plans are suggested for improving the 

 situation: the first is based on reorganization of routes whereby the number 

 of routes was reduced from 12 to 4 and the mileage was reduced more 

 than one third; the other was a reorganization of rate structure by zones. 



364 The Significance of Body Weight in Breeding for Egg Production. By F. A. 

 Hays. 16 pp. June 1939. 



An analysis of the records of 2,283 Rhode Island Red pullets showed 

 considerable parallelism between monthly body weight and monthly 

 egg weight and egg production. Maximum egg weight occurred about 

 one month earlier than maximum body weight, and the highest level of 

 egg production occurred when body weight was at its maximum in March 

 and April. Figures showed that removal of light-weight pullets on 

 March 1 is an effective means of reducing subsequent mortality. In 

 general, body weight offers a valuable guide to the breeder, particularly 

 from the standpoint of egg size and laying-house mortality. 



365 Product-Costs of Milk to Dealers in the Springfield Area, 1935. By Alfred 

 A. Brown and J. Elizabeth Donley. 28 pp. July 1939. 



Variations in product-costs (weighted average cost to dealers of milk 

 purchased from producers) in the area are analyzed and suggestions made 

 for reducing them. The milk industry can perform its most effective 

 service under conditions of relative market stability. Among conditions 

 found not conducive to market stability and orderliness are uneven 

 distribution of fluid outlets among dealers, rigidities in producer-distributor 

 relationships, and the absence of reasonable relationships between the 

 price payable for milk disposed of as fluid and as surplus. The disad- 

 vantages suffered by all producers, but mostly by producers with inferior 

 sales' outlets, should be minimized by the development and application 

 of a logical pricing technique based on "normal" class price relationships. 



366 Towards a Perfect Milk Market. By J. Elizabeth Donley. 28 pp. Novem- 

 ber 1939. 



A normal market should show little duplication of services in procuring 

 its milk and have little surplus at any time of year. This study made in 

 1935 showed Worcester to be such a market — the producer sells his 

 milk regularly throughout the year, the dealer has very little surplus to
