Profit in Woodlands 



There certainly is. To make it clear just how great the possi- 

 bilities are, we have published a highly instructive and unusually 

 interesting little book. It treats the subject from its smallest to 

 its largest sense — ^pointing out what can be done to increase the 

 value of wood lots of a few acres, up to large areas of forest lands 

 covering square miles. 



To give j'ou an inkling of what we do : One of our customers 

 was offered $400 for a cut of timber. Through our direction, $900 

 was realized. This case may or may not be an unusual one. 



A Southern timber syndicate has called us in to direct their 

 yearly cutting, so that in twenty years' time it can be profitably 

 cut over again. We will make it a perpetual source of income to 

 them as well as lay out its fire protection, see that no destructive 

 fungi or insects get the upper hand, and so on. But our book, 

 "Profit in Woodlands," goes into the matter from A to Z. Send for it.
