a very convenient manner, its motion is at all times perfectly

whatever may be the speed, it can be checked as desired." 
Where a large quantity of grain is 1o be threshed, a tvvo horse 
power would be preferred, as about double the quantity of grain 
could be threshed in the same time, and it is much easier for the 
horses, while the expense would not be much enhanced. 
These machines are manufactured by Messrs. A. & W. C, 
Wheeler, at Chatham Four Corners, Columbia co., N. Y., and 
sold by H. L. Emery, Albany. (See advertisement.) 
THE CYPRESS. 
There are two species of Cypressus known in the forests of 
the United States, under the name of Black Cedar or Cypress, 
(C. disticha,) and the White Cedar, (C thysides.) They both 
yield good timber. 
The C. disticha is abundant in the swamps of Virginia and the 
south, and forms the only tree in immense swamps on the Mis- 
sissippi. In these localities it often rises 130 feet, and attains 30 
to 40 feet girth at the earth, running up like a cone. The wood 
is extremely durable, and in high repute for shingles and posts. 
It is felled in winter and allowed to dry thoroughly before being 
split. The trees which grow in a great measure in water, have 
light barks, and are called white cypress, while those of dryer 
soils are called hlack cypress, and yield a firmer and more resinous 
wood. — Farmers^ Diet. 
The cypress of Louisiana and Mississippi, says Dickson and 
Brown, in a paper read before the Association of Geologists and 
Naturalists, is found to observe no very marked geographical 
prefereiKes, except so far as respects proximity to the Mississippi 
river and its tributary water courses. It is distributed about 
equally, over the alluvial lands embraced in these states; yet it 
is by no means interspersed equally among the other forest growth, 
but it observes certain special hydrographical positions more or 
less detached and of variable area. It attains its highest per- 
fection between the 31st and 32d degrees of latitude. 
Of the local causes which determine the distribution and growth 
of cypress timber, the most essential one is, that the soil in which 
it grows should, for the greater part of the year, be completely 
saturated with water. The country abounds in basin-like de- 
pressions of the general surface, into which flow the surplus 
waters of the surrounding forests; and there are also elongated
