and fir tribe. When the seeds are sown in autumn, immediately after being 

 gathered, they sometimes come up the following year. Cuttings should he 

 made in autumn, oi' the wood of the same year, with a small portion of the 

 preceding year's wood attached ; and they should be planted in sand, or in a 

 very sandy loam, in a shady border, and covered with hand-glasses. Cuttings 

 put in in September will form callosities at their lower extremities the same 

 autumn, and should be protected by mats during severe frosts in winter: the 

 following autumn they will be ready to transplant. Layers may be made 

 either in autumn or spring.

Derivation. From thyon, sacrifice ; in consequence of the resin of the Eastern variety being used 

 instead of incense in sacrifices. Why it was called Arbor Vita? is uncertain. Parkinson says the 

 American species was presented to Francis I. under this name, and that it has been continued 

 ever since, though for what reason he knows not. It was called the Arbor Vita? by Clusius. 

 Roylc mentions that, in the East, the cypress is called the tree of life ; and that its berries, &c, are 

 considered a cure for all diseases.
