be either circular or fquare, as will be-moft convenient, the larger 
the better ; and on the upper part of the Tides there may be four or 
five little openings wired, with doors to each, for the fake of giv- 
ing air all round upon fome occafions. Care mu ft be taken not to 
expofe the young plants to ftrong funftiine : foraetimes, when the 
lid and doors are open, it may be neceflary to throw a matt or thin 
cloth over them, but this muft depend on the judgement of the 
perlon who has the care of them ; there fhould be handles fixed to 
the Tides, to move it with more fafety. 
There fhould be a layer of wet mofs, of two or three inches 
deep, at the bottom of the box or calk ; or, if that cannot be got, 
lome very rotten wood or decayed leaves, and then frefh loamy 
earth, about twelve inches deep, both of which will fink to a foot 
deep: the wet mofs is intended to retain moifture, and to keep the 
earth from drying too foon. 
The furface of the earth fhould be covered with mofs cut fmall, 
which now and then on the voyage fhould be wafhed in frefh 
water, and laid on the earth again to keep the furface moift, and to 
wafh off mouldinefs or faline vapours which may have fettled on 
it. When the plants come up, it will be proper to fave what rain- 
water can be got, which will encourage their growth, and be of 
more fervice than the water drawn out of calks that have been 
long on board the fhip. 
Thefe kind of boxes or cafks will be very proper to fow many 
forts of fuch feeds in as are fo difficult to be brought from China, 
and other parts of the Eaft-Indies, to Europe in a vegetating ftate ; 
fuch as the lechee, mangoes, mangofteens, pepper, marking nuts, 
various forts of peaches, rofes, oranges, citrons, lemons, &c. 
And nothing can be more convenient than thefe cafks, for fend- 
ing olive plants, capers, young vines, &c. &c. to our diftant Ame- 
rican plantations. The fize may be varied as the plants to be lent 
may require.
