treated with this preparation produced crops exceeding those from the untreated plots by as 

 much as 26.7 per cent. It is stated that the treatment of non-legumes with cultures of bac- 

 teria is still in the experimental stage. — Lewis T. Leonard.

 to cost of production and distribution of income. Philippine Agric. 8: 213-233. 1920. — The 

 general conclusions are that lowland culture gives a higher yield than upland culture, but 

 the cost per unit area is higher. — E. D. Merrill.

1125. Kiesselbach, T. A., and F. D. Keim. The regional adaptation of corn in 

 Nebraska. Nebraska Agric. Exp. Sta. Res. Bull. 19. 64 p., 13 fig. 1921. — The general mor- 

 phological characters of the plant and the histological structure of the leaf were studied for 

 corn types known to be acclimated to various regional areas of Nebraska. Adaptation of 

 corn to divergent climatic conditions consists in a morphological rather than in a histological 

 reaction. While some of the vegetative characters, such as total leaf area and plant weight, 

 may differ as much as 300 per cent, in the case of native types growing in the more adverse as 

 compared with the most favored parts of the state, no important histological leaf characters 

 exhibited a difference of more than 15 per cent. — The actual hereditary difference (apart from 

 environmental effects) between types adapted to favorable and to unfavorable climatic con- 

 ditions may be brought out by comparing both in the same environment under favorable 

 conditions. When eastern and western Nebraska corn were grown comparably at the Nebraska 

 Experiment Station in Lancaster County, western Nebraska corn was much reduced in plant 

 size, leaf area, and dry matter. Plants from seed of both sources were rather similar as to leaf 

 thickness, epidermal and cuticular thickness, relative number of vascular bundles, number 

 of Btomata per unit leaf area, and size of stomata. It is concluded that adaptation of corn to 

 a region of moisture shortage consists chiefly in the reduction of vegetative development and 

 consequent reduction in the amount of water used by the individual plant. Comparative 

 yield tests of corn from various sources indicate that, in general, native seed is superior to 

 imported seed, though it is possible to introduce seed from a distance which gives entirely 

 satisfactory results. — T. A. Kiesselbach.

 Africa 2: 409^21. Fig. 1-7. 1921. — The author discusses the best methods of handling 

 Turkish tobacco in the Western Province of South Africa. Ripening, harvesting, and curing 

 are treated in separate paragraphs. There are 3 stages of curing: 1st, wilting in a wilting 

 room; 2nd, drying in the sun; and 3rd, fermentation. Each stage is described in detail. —

 tests and breeding work with numerous varieties of diversified crops were conducted. One 

 thousand acres of pigeon peas were planted as a result of the Haiku demonstrations. —

 area for potato culture, it is imperative to produce more on a given area. In this connection, 

 the importance of extensive use of farm machinery, better organization and utilization of 

 labor, proper fertilization, and the use of good seed are discussed. — M. Shapovalov.
