144 America's Crop Heritage veniently done, they may be taken up with a ball of earth about the roots, and the roots of each surrounded with wet moss, carefully tied about it to keep the earth moist. They may afterwards be put into a box, and each plant secured by laths fastened crosswise above the roots, and the interstices between the roots filled with wet moss. The same methods may be observed with young grafted or budded fruit trees. "Where the time will permit it is desirable that the roots of the plants be well established in the boxes in which they are transplanted. Herbaceous plants require only a short time for this; but, for plants of a woody texture, two or three months is sometimes necessary. "Boxes for the conveyance of plants, or of seeds that are sown, may be made about two feet broad, two feet deep and four feet long, with small holes in the bottom, covered with a shell, or piece of tile, or other similar sub- stance, for letting off any superfluous water. There should be a layer of wet moss of two or three inches deep at the bottom, or, if they cannot be had, some very rotten wood or decayed leaves, and upon that about twelve inches depth of fresh loamy earth, into which the plants that are to be transplanted should be set. The surface of the earth should be covered with a thin layer of moss, cut small, which should be occasionally washed in fresh water during the voyage, both to keep the surface moist, and to wash off mouldiness, or any saline particles that may be on it. "When the boxes are about to be put on board the ship, hoops of wood should be fastened to the sides, in such a manner that arching over the box, they may cover the highest of the plants; and over these should be stretched a net work of pitched cord, so as to protect the plants from external injury, and prevent the earth from being disturbed by mice or other vermin. "To each box should be fastened a canvass cover, made to go entirely over it, but so constructed as to be easily put on or off, as may be necessary to protect the plants from the salt water or winds, and sometimes from the sunshine. Strong handles should be fixed to the boxes that they may be con- veniently moved. "During the voyage, the plants should be kept in a light airy situation; without which they will perish. They should not be exposed to severe winds, nor to cold, nor for a long time to too hot a sunshine, nor to the spray of the salt water. To prevent injury from the saline particles with which the air is oftentimes charged at sea, (especially when the waves have white frothy curls upon them) and which, on evaporation, close up the pores of the plants, and destroy them, it will be proper, when they have been exposed to them, to wash off the salt particles, by sprinkling the leaves with fresh water. "The plants and seeds that are sown, will occasionally require watering on the voyage; for which purpose rain water is best. If, in any special case, particular instructions upon this point, or upon any other connected with the management of the plants during the voyage, be necessary, they should be made known to those having charge of the plants. But after all, much will depend upon the judicious care of those to whom the plants may be confided during the voyage. "Plants of the succulent kind, and particularly of the bulbous family should not be planted in earth, but in a mixture of dry sand, old lime,
