The "Wolmanized*" mark on the lumber you sell certifies three things:

1. Protection with a treatment that has 30 years' record of reliable results.

2. Protection by proper, scientific handling during treatment.

3. Protection to your profit.

Wolmanizing is a process of forcing Wolman Salts* into lumber under great pressure. These salts absolutely prevent decay and termite damage. Yet Wolmanized lumber has all the advantages of ordinary wood. Clean, odorless, and noncorrosive, it can be nailed and painted and stained. The treatment also makes the lumber slightly fireretardant.

Protection to your profit comes from the fact that Wolmanized lumber is sold only through regular trade channels. Leading producers carry stocks, so you can obtain straight or mixed carloads. Any lumber en route to you may be treated economically at a conveniently located plant.

Selling Wolmanized lumber helps you get new business. Ask us for details about the ways aggressive dealers are using it as a selling point, for their yards. AMERICAN LUMBER & TREATING COMPANY, 1405 Old Colony Building, Chicago.
