It is a(hnitteeen si^asoned out of doors, allowing the outer part of the wood to become so hardened as to prevent the dampness in the wood from exuding, and this interic^r dampness ferments and decays. Hence, in former methods of preserving, the sap has been expelled l)y pressure and the vacuum filled with chemicals. But we now find that tlu> decay is from the outside — where the wood is damp and not accessil ' *^o light and air.

Fincli, of Toronto, Canada, has introduced a pre- servative which \)y al)so!-[)ti()n and eapilhiry attraction pene- trates tlie wood, which is porous, and, nnxin^r with tlie sap or alhuuien of the wood, makes it a preservative — fillincr aiid closing the pores, thei'el)y preventing interior fennentation or (U'cay, aud no fungous growth can aftect it from the (aitside. In 1875 tw(j-incli pine planks and four-by-four scantlimAs for sidewalks were coated with this cheap and powerful pre- servative, and laid, at the re([uest of the City Council, in different wards of the city of Toronto, and after eight years' use, wei-e found to he perfectly sound — only worn thin and uneven, the knots protruding. Sample planks and scantlings of that lund)er can now be seen, which, on being cut, &iv, found to have retained even the pine smell, (juite fresh. The explana- tion is, that when lumber is so treated tlie destructive fun(»-us cannot grow upon it, and it becomes hardened, seasoned, and not subject to decay. This preservative has been used f(n- railroad ties, railway platforms, warehouse floors, sidewalks, scber which w^as laid on Yonge street, after eight years' use, was worn -7— unevoTi, tho knots prf)trurling.
