Show Alkali-Resisting Plants. It is frequently assumed that where soil shows surface incrustatian of alkali salts, it is valueless for agricultural purposes. This is shown not to be the case' by some experiments made by the Wyoming Government Experiment Station. There are, however, few plants so alkali proof as to flourish under these conditions. Incrustation of ordinary white alkali on the surface is usually marked, at least during dry weather, where there is as much as 1J or 2 per cent., of salts in the top two inches of soil. Such an amount of salts will prevent the growth of any of the cereals or of alfalfa. Barley or rye seem to stand more alkali than wheat or oats. In the germination of ,-eeds it was found that the iniliience of small amounts of alkali hastens spi outing and also "assists in the life of the plant, either stimulating growth or acting directly as plant food. " It did not appear ap-pear that any of the salts except com- 1 nion soda exerted directly poi-nnnus or corrosive effects on the .-cods. The injury in-jury apin-ar.-d due to the fact that the salts in solution interfered with the absorption by the seed of the water ' necessary for germination.
