The original growth -of timber on the upland has been 

 all cut off. The growth of the j'oung timber is rapid; 

 from fifteen to twenty years is long enough for it to get 

 sufficient size for fire-wood, and it is then cut off". An acre 

 cut off" in this way will yield about as many cords of wood 

 as it has been years in growing; thus, a twenty years' 

 growth will turn out twenty cords per acre. Last year 

 there was cut and sold 15,408 cords of wood in the county. 

 Its average price at the landings is about f2.75 a cord. 

 With land at a low price, the gtowing of fire-wood has in 

 many cases been found profitable. The greatest drawback 

 to this business are the fires, which are too common, and
