 Tahles are given showing the l>los>oniiii'_ r . leafing out, and ripening periods of plums 

 and cherries tor the years L903 to 1905, inclusive. The data show a close relation-

Growing* fall bearing- strawberries, S. Cooper | Amer. Agr., :: I 1906), No. /■-', />. 

 429, fig. /). — The Pan-American ami Autumn varieties of strawberries that hear fruit 

 in the fall are described and methods given for their cultivation. In the case of the 

 Pan-American variety it is stated that by judicious cultivation and systematic 

 removal of the early blossom stems this variety will continue to hear until the green 

 berries are frozen. An illustration is given of the plant in blossom and fruit. 



The transportation of fruit in refrigeration, < i. H. Powell ( ( '"/. Fruit Growi r, 

 S3 {1906), Nos. 919, pp. 1,3; 920, p. 5).— A paper presented before the American 

 Society of Refrigerating Engineers at its meeting in New York, December 4, L905, 

 in which the losses that occur in shipping perishable fruits in refrigerator cars are 

 discussed. 



Where fruits are shipped from the orchard without first cooling and are from 3 to 

 10 days in transit, large losses occur, particularly in the top tiers of fruit. The prob- 

 lem to be overcome is to secure refrigeration which will be sufficient to cool down all 

 parts of the car sufficiently to prevent the development of decay, either by improved 

 methods of car refrigeration or by cooling down the fruit before it is placed in the 

 refrigerator car. Coupled with these requirements is the necessity of having the car 

 refrigeration simple so that an ordinary brakeman could manipulate it satisfactorily. 



The cocoanut and its relation to the production of cocoanut oil, II. S. 

 Walker {Philippine Jour. Sci., 1 ( 1906), No. l, pp. 58-81, pis. 10).— This is a report 

 of an extensive study of cocoanut production from the standpoint of quality and 

 quantity of the oil yielded. 



Analyses are given of the seashore and interior soils on \\ hich cocoanuts grew suc- 

 cessfully, and of nuts picked at varying Btages of ripeness, nuts from different locali- 

 ties, and nuts grown on both sandy soils and clay soil.-. It had heen noticed that 

 cocoanut trees growing near the seashore at San Ramon produced much more fruit 

 than trees standing farther inland. Analyses showed the inland soils to he some- 

 what superior in the elements of fertility to the seashore soils, hut were much less 

 permeable. 



The following table shows the fertilizing constituents contained in the husk, shell, 

 meat, and milk of cocoanuts:
