Baron Voght has conceived the idea of expressing the capacities of soils 

 for cultivation, by figures, in a very ingenious manner, but we fear rather of 

 too intricate and fanciful a nature to be of much use. He expresses the 

 fertility of a soil by the produce of two numbers or factors, representing 

 riches and power, which are multiplied into each other ; for example, if the 

 power of a soil be 8°, and the riches 45°, the fertility will be 560°. By 

 power he understands the inherent properties of the earth which compose 

 a soil, exclusive of organic matter ; by riches he understands the organic 

 matter contained among the earths; and by fertility, the power of the 

 earths and the organic matter combined, or the power of what is called soil 

 in the proper sense of that term. Having determined the degree of fertility 

 necessary to raise different crops, in preparing a field for any of them, the 

 square root of the fertility of the crop is to be compared with the power 

 and riches of the soil, and the number or factor of the former, if deficient, 

 is to be raised by mechanical operations, or the mixture of other earths ; 

 while that of the latter is to be raised by manures. Provided the V 2 of 

 the requisite degree of fertility be produced, the Baron is indifferent whether 

 it arise from power and riches, or power only. This key to the Baron's 

 system will enable any reader of a mathematical turn to apply it to almost 

 every part of agriculture. As an ingenious fancy, we have thought it worth 

 noticing, with a view to the mental exercise of young cultivators.

 sands culturable. Berlin, 8vo. 



A variety of plants are recommended to be planted with a view of fixing 

 light inland sands, and the common pine as the best.

This agricultural newspaper appears weekly in Stuttgard, and sometimes 

 contains ingenious papers on rural subjects. M. Jaeger (p. 139.) has long 

 experienced the good effects of watering frozen vines in the spring, rather 

 than leaving them to be thawed by the sun. He proposes to extend the 

 practice to vineyards, making use of fire-engines for distributing the water. 

 Professor Schoen (p. 190.) states that every description of bread corn, when 

 intended for seed, should attain complete maturity before it is reaped ; but 

 on the contrary, when corn is intended to be converted into flour, it should 

 be cut eight or nine days before it be fully ripe. Experience, he says, has 

 fully proved, that such grains as from their maturity detach themselves from 

 the ears, always produce the finest plants, from being larger and more per- 

 fect in their conformation. The proper period for reaping corn destined for 

 the mill, is when the grains being pressed between the fingers }'ield to it, 

 and become a viscous mass. It requires a longer time to dry before it can 

 be carried to the rick-yard, but the flour produced from it is much more 

 white, and more abundant, than from matured grain. In some parts of Hun-
