Very few so far as we know ever think of using putty to the outside of sash in our country. The glass is bedded in soft putty, then fastened in with triangular tin sprigs, and neatly painted. It does not appear, however, to have made much headway in the Old World, a correspondent of the Journal of Horticulture says that this " system of glazing is not adopted so generally as I believe it deserves. One trial, I am confident, will convince anyone of its superiority, provided certain conditions are carefully attended to. Repairs will be less, the appearance is very little effected, and the house will prove more durable than when top putty is used." The heats and colds of our country makes the best putty work crack and shrink from the wood; and, unless the pitch is steep, puttied houses leak dreadfully.
