Louisiana. Mississippi, and Alabama. — In Louisiana walnut is not 
found in the pine type and is rare in the alluvial bottom-land type — 
the two types which comprise by much the greater part of the forest 
area : but commercial amounts are sometimes found in the Red River 
Valley, in the northwestern corner of the State. In Mississippi wal- 
nut is widely scattered through the extensive alluvial bottom hard- 
wood type, but is so scarce that shipments of logs from any part of 
the State are rare. Alabama has never figured as a walnut-producing 
State, most of this species being found in the northeastern part, in'the 
valleys of the Tennessee and Coosa Rivers. 
FUTURE SUPPLIES. . 
The future supply of walnut can not well be inferred from any 
statement of the present stand of merchantable timber, because in 
such a statement immature trees are not considered. An estimate of 
the average annual yield is much more expressive of what may be 
expected in the future. Previous to the war the average annual cut 
probably ran between 40 and 50 million board feet a year, and those 
most familiar with the situation believed that this represented fairly 
well the cut that might be sustained continuously. This was borne 
out by the discovery during the war that the country actually had 
much more merchantable walnut than anybody supposed, although 
the increase was due in part to closer utilization and tlie release, as 
an act of patriotism, of supplies not usually on the commercial 
market. The war cut heavily into the growing stock, however, and 
the yield for some years will be reduced. Nevertheless, if the amount 
of young growth is in normal proportion to the older trees there is 
no reason why the old sustained yield of 40 to 50 million board feet 
should not be resumed. 
An estimate of the amount of immature timber is even more diffi- 
cult to make than an estimate of the merchantable stuff. Among 
those informed, the opinion is common that in most of its range there 
is an abundance of young walnut down to 6 or 8 inches in diameter. 
There is an astonishing lack of reproduction below this size, except 
in the upper Ohio and eastern region. The trees now rated as un- 
merchantable — and this is particularly true in the western part — 
are, as a rule, not thrifty young trees, but older growth that has been 
suppressed and stunted, though still capable of recovery and of de- 
velopment into saw timber. From this source there is a fair assur- 
ance of a moderate supply of black walnut for. perhaps, 30 years, 
comparable in amount to the walnut cut during the 20 years before 
the war. If a great war should occur during the next 30 years much 
difficulty would be experienced in securing desirable amounts of 
walnut. It is too late now to provide for any material increase in
