**ARCUTION**, in gardening, the method of raising trees by layers, which is done in the following manner:

Strong mother-plants or stools must be planted in a clear border, and in a straight line, about six feet apart. When these have shot five or six main branches from the root, and as many collateral branches, the former must be bent to the ground, and there fastened. The small branches must be covered three inches deep upon the joints, and have a large basin of earth made round them to hold the water.

About the middle of September, they may be opened, ed, and, if they have taken root, may be immediately removed into the nursery; but if they have not sufficiently extended their roots, they must be suffered to remain till the spring, and then transplanted.
