close grain, very durable, and of a beautiful reddish hue, which Pliny says it 

 never loses. The rate of growth, in the climate of London, will average, for 

 the first 8 or 10 years, from 1 ft. to 1 ft. Gin. a year ; after which the tree 

 grows more slowly ; and, when it has attained its full size, and is between 

 30 ft. and 40 ft. high, it will live many years without any perceptible increase 

 in dimensions. Any common garden soil suits the cypress ; but it attains its 

 largest size in such soils as are rather dry and deep, and in situations sheltered 

 rather than exposed. It may be propagated either by cuttings or seeds ; the 

 former being put in in autumn, and treated like those of Thuja. The cones, 

 which appear to be ripe in autumn, are not perfectly so, but require to hang 

 on the trees till the following March or April. They may then be gathered, 

 and placed in a warm room, or in a box or basket, and set in a dry stove. In 

 a few days the scales will open, when the cones may be thrashed and the 

 seeds collected : they may be immediately afterwards sown, and treated like 

 those of the Jbietinae. In England, it is common to sow the seeds in flat 

 pans or in boxes ; because, as they are somewhat tender when they first come 

 up, they admit of being more readily protected by being carried to a pit. 

 Unlike the seeds of the genus Thuja, which commonly lie in the ground a 

 year, those of the cypress come up in three or four weeks. They grow to 

 the height of 3 or 4 inches the first season, and may be transplanted into pots, 

 and kept in a pit through the winter. At the end of the second autumn, they 

 may be planted where they are finally to remain ; but, if it be thought neces- 

 sary, they may be kept three or four years in pots ; shifting them frequently, 

 or allowing them to remain in the pot unshifted, according as the object may 

 be to produce large plants, or to concentrate the roots in a small ball, so as 

 to occupy less space in sending the trees to a distance. When the cypress is 

 planted where it is finally to remain, and the situation and soil are suitable, it 

 may be said to require no farther attention during the whole of its existence. 

 It always grows erect, so that no care is requisite to train up a leading shoot ; 

 and, as its branches occupy little space, it seldom or never requires pruning.
