color of the grain. There was a marked loss in vitamin A and moisture after the plants 

 had attained maximum growth. This loss of vitamin A in mature corn fodder is a factor 

 to be considered in the use of fodder as an animal feed. The grain of yellow maize lost 

 much of its vitamin A as it matured and dried out. 



266 Some observations on internal cork disease of apples in Massachusetts. J. S. 

 Bailey and W. H. Thies. Amer. Soc. Hort. Sci. Proc. 34:187-19L 1937. 



During the season of 1936, an internal browning of the fruit of certain Mcintosh and 

 Cortland trees attracted considerable attention in Massachusetts. Our observations 

 show that this disease is not limited to any one soil type, it occurs where the subsoil is 

 unfavorable for root penetration, and is partially prevented by a heavy mulch. Trees 

 with a shallow root system, from whatever cause, are at a distinct disadvantage in a time 

 of drought. They may be unable to obtain an adequate supply of moisture during a part 

 of the growing season, and it seems reasonable that this would prevent a normal develop- 

 ment of the fruit. This association of the disease with water deficiency has been reported 

 by several workers. 



267 Tomato variety and strain differences in ascorbic acid (vitamin C) content • 

 W. A. Maclinn, C. R. Fellers and R. E. Buck. Amer. Soc. Hort. Sci. Proc- 

 34:543-552. 1937. 



Ninety-eight distinct varieties or strains of tomato grown under constant field condi- 

 tions were found to vary in vitamin C content from a maximum of 249 to a minimum of 

 74 units per ounce. Different strains of the same variety showed marked differences in 

 vitamin C. No correlation was found between size of tomatoes or degree of ripeness and 

 vitamin C content. Data on storage tests indicate that the vitamin C of tomatoes is not 

 seriously affected during shipment, in markets, or at canneries so long as the fruits remain 

 firm and sound. 



268 The Fungi of Nantucket. Century I. E. F. Cuba. Rhodora 39:367-376. 

 1937. 



Dotted with ponds and bogs and sometimes enshrouded by heavy fogs and storms. 

 Nantucket provides conditions which are especially favorable for a rich fungus flora and 

 for epidemics of plant diseases. It is the hope of the author to make a fairly complete 

 collect'on of the fungi of these islands and to publish the material in sets of centuries. 

 This paper is the first of the series. 



269 A photo-electric Tyndall meter. \V. S. Mueller. Food Research 2 (1): 

 51-54. 1937. 



The instrument here described was developed for the purpose of studying the effect of 

 temperature treatments on the light-scattering ability of gelatin sols and gels, where a 

 a need was felt for an instrument extremely sensitive to light intensity. 



270 Stability of vitamin C in sweet corn to shipping, freezing, and canning. 

 C. F: Dunker, C. R. Fellers, and G. A. Fitzgerald. Food Research 2 (1): 

 41-50. 1937. 



Raw, fresh-cooked, frozen, and whole-grain canned sweet corn are all moderately good 

 sources of vitamin C (40 to 60 international units per ounce). Cream-style canned corn 

 is a little lower than whole-kernel. Little loss in vitamin C occurs after picking and 

 storage in the husk for a few days. Similarly, frozen corn can be defrosted and canned 

 corn kept in the refrigerator for several hours after opening without appreciable loss of 

 vitamin C. 



271 Hatchability as related to seasons and hour of laying. F. A. Hays. Poultry 

 Sci. 16 (2):85-89. 1937. ^ 



Under the conditions of incubation used, late hatching increased hatchability for hens 

 but not for pullets. Hour of laying appeared to have no significant effect on fertility, 

 embryonic mortality, or hatchability of fertile eggs. 



273 Some milk superstitions. J. H. Frandsen. Jour. Home Econ. 29 (4):242-243. 

 1937. 



The author unmasks some of the old superstitions regarding milk, in the hope that a 

 knowledge of the facts will lead to an increase in the use of one of our best foods. 



274 Careful culture recommended to avoid canker on gardenias. Harold E. 

 White. Florists' Review, February 25, 1937. 



This paper describes symptoms, the part of the plant affected, possible means of infec- 

 tion, and cultural methods which should keep the disease from becoming established.
