564 COTTAGE, FARM, AND VILLA ARCHITECTURE. 1222. TugweWs Mode of Slating. The chief peculiarity of this mode consists in using rebated laths ; the upper half of the lath rising above the lower half, as much as the thickness of the slate ; by which means the slate incumbent on the upper part can be nailed in its middle. The laths are 2 inches wide and an inch thick. Fig. 1099 is a section of j)art of a roof slated in this manner : in which a is a rafter ; b, the laths; and c, the slates. Fig. 1100 is a plan, or vertical profile, of a portion of the 1099 110") same roof. " The laths, in the mode of slating generally practised, are made of deal only an inch in width ; and, as a nail piercing the slate lying on such inch-wide laths will appear to have fastened it to the middle of that inch, the slate, with tiie wind lifting at its lower end, becomes a lever, with its fulcrum at the head of the nail ; its short arm being only half an inch in length above the nail, and its longest arm (supposing the slates as in tlie figure, to be 18 inches long) 17 inches and a half below it ; thus giving the wind a power to raise the slate as 35 to 1. In the method here proposed, that power will be only as 1 1 to 7 ; the short arm of the lever, in this case, being 7 inches long, and the otlier arm only 1 1 inches ; which will, in all probability, enable the slate to resist the most violent hurricane or tornado evei experienced in Europe."

That, in point of accommodation, no inconvenience will result from rendering a farmery architectural, will, we think, be obvious from going into the details of fig. 1095 ; in which are shown, a family potato-house, a ; poultry-house, h ; family cow-house, c ; gig-house, d; gig and riding-horses table, e; gateways, /; tool-house, </ ; carpenter's shop, h ; smith's shop, i ; bailifTs house, k ; house for boiling or steaming food for the pigs, family cows, and saddle-horses, I; cart-sheds, m; unthreshed corn barn, n; straw- room, o ; place for boiling horse food, p ; loose horse stable, q ; stables for eighteen horses, r ; fodde ring-bay, s ; house for a bull, t ; hospital or house for a sick animal, )/ ; implement-house, v; cattle-sheds, a-; pigsties and calf-pens, x ; open space between the
