DISTRICT WEST OF THE TENNESSEE RIVER. 3r 
red and fiftieth of these forests is likely to be called for per 
annum, at any time, in the immediate future. At this rate: 
they can easily reproduce themselves, with the exception of 
the white oak, which does not tend to perpetuate itself. Of 
course,the avaz/ab/e timbers will be the ones drawn upon, and 
they would be exhausted in a few years, comparatively, at 
such a drain as I have considered possible in the future. 
4. The white oak forms about thirty-two per cent. of the 
forest timbers in the Purchase, and, alone,would be worth, at 
‘Paducah, the enormous sum of $3,000,000 to $5,000,000. 
The total forests of the Purchase are estimated at from ten 
to fifteen millions of dollars in value.
