​MOSS.—This vegetable production being very detrimental to the growth and health of fruit-trees, Mr. Forsyth advises it to be carefully removed in the months of February or March; after which the scraped trees must be washed with a mixture of fresh cow-dung, urine, and soap-suds.—If this operation be repeated in autumn, when the trees are destitute of leaves, it will not only prevent the production of moss, but will also destroy the eggs of numerous insects, that would otherwise be hatched; while it contributes essentially to promote vegetation.
