A descriptive catalogue of useful fiber plants of the world : including the structural and economic classifications of fibers . r bottoms,are best adapted to this culture, therefore, is quite general along the smaller streams of Brittany, wheretlie climate is mild and the atmosphere humid; and in Kentucky the best lands onlyare chosen for hemp, and the most favorable results being obtained where there isan underlying bed of blue limestone. As a general rule, light or dry soils or heavy,tenacious soils are most unfavorable. Hemp is not considered a very exhaustive crop. It is stated by a successful Ken-tucky grower that virgin soil sown to hemp can be followed with this crop for fifteento twenty years successively; alternating then with small grain or clover, it can begrown every third year, without fertilizers, almost indefinitely. In France a rotationof crops is practiced, hemp alternating with grain crops, although competent authori-ties state that it may also be allowed to grow continuously upon the same land, butnot without fertilizers. Regarding this mode of cultivation, they consider that it is.

If the soil is not sufficiently rich in phosphates or the salts ofpotassium, these must be supplied by the use of lime, marl, ground bones, animalcharcoal, or mixed with prepared animal compost. Even hemp cake, the leavesof the plant, and the shive, or boon, maybe returned to the land with high fertilizing is necessary, as the hemp absorbs the equivalent of 1,500 kilosof fertilizers per every hundred kilos of iiber obtained. In Japan, where most excel-lent heuip is produced, the ground is given a heavy dressing of barnyard manurebefore it is plowed in November. After the soi
