1096. Cruess, W. V. Lessons for prune growers from the September rains. Monthly 

 Bull. Comm. Hortic. California 2: 53-60. Fig. 27-83. 1919.— With normal seasons, the Cali- 

 fornia prune grower feels no concern regarding probable showers during the drying season. 

 In September of 1918, however, heavy rains fell and were followed by a long period of warm, 

 moist weather resulting in an enormous loss of prunes. The usual methods of handling wet 

 prunes failed because of the adverse weather conditions. Sulfuring of this fruit, h< 



by exposing it on trays to the fumes of burning sulfur for two hours, checked molding and 

 fermentation and made it possible to dry the fruit satisfactorily. The sulfured product 

 excellent in flavor and appearance and found a market. Fermented dried prunes can be 

 separated from the sound fruit by flotation in water in a 5 per cent salt solution or a 10 per 

 cent glucose solution. The damaged fruit could be most satisfactorily utilized by feeding 

 it to hogs. — E. L. Overholser.

 Two general types of submerged leaf occur, one ribbon-like and more divided than aerial, 

 other broad and thinner. Author refers to heterophylly in terrestrial angiosperms and 

 juvenile forms of conifers; demands interpretation of heterophylly that will cover all ca 

 Author recalls observations in Sagittaria that aquatic and aerial leaves are differentiated in 

 submerged bud; that first leaves are ribbon-like even when young plant is terrestrial; ami I 

 this juvenile type can be induced again in maturity by weakening conditions, such as re- 

 moval of roots. Also refers to Burns' conclusions on Proserpinaca palustris that aquatic 

 condition is not cause of leaf division. For old conception of heterophylly as induced by
