On account of the adhering sea-water, sea-weed may also SEA-WEEDS 71 be injurious to hops, to the burning quality of tobacco,and it may depress the sugar content of beets. It is be-cause of this well-recognized action that it has becomecustomary, in certain countries, to allow the sea-weed tobe leached by rains before carting it upon the land used forfarming purposes. The same result is often accomplishedin part on the coast of New England, without thought of. Fig. 6. — Sea-weed for rock-weed (Fucus vesiculosus). this feature, by the practice in times of storm of cartingthe sea-weed into piles a short distance from the shore,until a favorable opportunity is presented for hauling itaway. This possible danger from the use of sea-weedmay be very largely or wholly obviated by applying iteither the autumn or winter previous to the time whencrops subject to such injury are to be grown. 99. Sea-weed quick in its action. — Owing to itsundergoing ready decomposition, sea-weed is to be classed 72 FERTILIZERS as a quickly acting manure, which exerts its chief effectsthe first season. 100. Sea-weed compared with farm-yard manure. —In the Western Islands, a load of farm-yard manure isconsidered as being equal to two and one-half loads offresh sea-weed, or to one and three-four
