PREPARED

ASPHALTE ROOFING FELT.

[Ill.u.s.tration]

This new prepared production is ready coated, and can be applied on the roof without further trouble. It is easy of application, and does not require any repairs for a long time. It is more durable than some slates, and has been found a suitable subst.i.tute for iron or tin roofs. It has a sanded or stony surface, which renders it UNINFLAMMABLE and FIRE-PROOF. Exposed to the most intense fire, and sparks falling upon it, it will not propagate the fire. Under the influence of the sun it will not run, which makes it specially adapted to hot climates. Its easy application and pleasing appearance have made it a favorite roofing material throughout all the Indies and other colonies. Being not c.u.mbrous for transport, it is of invaluable service to settlers and farmers in far remote districts. When used for temporary purposes it may be taken off and applied again to another construction. It replaces common Asphalting on Terraces, Lobbies, Counting-houses, Office Floors, etc.; is a great preservative against dampness and vermin, and equalizes the temperature. It is 32 inches wide, and made in rolls of 25 yards each. Send for circular to
