tors but the general features Of the nvention-a mode
of building which di-penses with any heavy timber,
and makes comfortable cabin by the aid simply of
large wagon load Of suitably prepared material, and
with only few hours labor--prepossesses lis very
much in its favor 1t the intention of the parties in

vond the borders of civilization, where by the aid Of
suitable machinery the lumber and the iron tastenings
will be prepared complete and sold to the hardy emf

One Of the most marked peculsrities of the inven-
ton is that by which the contraction and expansion of
the wood is allowed for. 1t happens that lumber is
continually changing It's dimensions by reason of iu-
bbirg or evaporating moisture. The fbers do not
engthen but they become thicker or, what is the
same thing stand farther apart with each accession of
watery particles. This shrinking and swelling of the
material is provided for in Ftzgerads cabin by laying
all the boards in horizontal courses fitted tightly to-
Qether and not fixing to any uprights, but leaving
them free to slide up and down in what il equivalent to
grooves of their ends. The cabins all two stories
high and the weight of the roof also of the floor Of
the second story presses directly upon the edges of the
boards forming the Sides The result Of this arrange

Geo. Hutton's device for growing to any required
depth or width with single circular saw is decidedly
the simplest and cheapest growing apparatus yet ex

observer of nothing but ordinary circular saw flor

easily and rapidly adjusted by means OF small side
screws on the washers, and can be made to groove

quarters of an inch. This device was patented onv
few months ago, and is materially different from any
method Of adjusting for this purpose before In use
