ASPHALTE ROOFING FELT.

[Illustration]

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 substitute 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 cumbrous 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
