 ington [D. C] Acad. Sci. 10: 505-508. 1920. — Two new species, A. obtusifolia and A. Con- 

 zattii, are described and A. raccmosa (Schaefferia racemosa DC.) appears as a new combina-

1575. Fontanel, P. Sechage des plantes pour herbiers. [The drying of plants for her- 

 baria.] Nat. Canadien 47: 51-61. 1920. — The author notes the common and the complicated 

 processes of drying plants and proposes an intermediate process depending first on drying 

 under the usual pressure of absorbent layers but at a higher temperature, to accelerate the 

 evaporation of moisture and forestall the degenerative action of enzymes and bacteria. This 

 requires a current of heated air, the temperature being first between GO and 70°C. Later 

 the temperature should be considerably lowered. A box holds the plants over a suitable 

 source of heat. Between the specimen sheets are sheets of tubed cardboard through which 

 the upward current of warm air passes. Methods for treating certain plants with chemicals, 

 to preserve color, elasticity, etc., and to prevent decomposition, are also considered. — A. H. 

 Mac Kay.

1578. Newton, R. The quality of silage produced in barrels. Jour. Amer. Soc. Agron. 

 13: 1-11. 1921. — Judging by the odor, appearance, palatability, and chemical tests, barrels 

 were found to be suitable experimental containers for silage. Silage from barrels was found 

 to compare favorably with silage from farm silos. — F. M. Schertz. 



1579. Pathak, G. p. Some famine foods in Ahmedabad. Agric. Jour. India 15:40-45. 

 1920. — New materials which have been utilized as famine food are Bid (rhizomes of Scirpus 

 kysoor), Thek (rhizomes of Cyperus bulbosus), Poll of pan (the inflorescence of Typha angus- 

 tata), and tubers and fruits of poyana (Nymphaea stillata). Bid contains about 70 per cent of 

 digestible carbohydrates and 8-10 per cent of proteids. When used for human food the 

 clods dug from the soil containing the rhizomes are left unbroken until thoroughly dried. 

 The thek plant grows naturally in salt land; when properly dried and roasted it is used for 

 flour. Poyana is the common water lily of the nal. The tubers are roasted in ashes or are
