TIMBEE OF THE UNITED STATES AND CANADA 71 
After open-air seasoning for about three months, and 
taking the average over 300 fair-sized logs, the weight of 
pitch;; pine worked out at 45*8 lbs. per cubic foot; the 
minimum was 35*5 and the maximum 54'6, The percentages 
of weights were as follows : — 
5 per cent, under 40 lbs. per cubic foot. 
27 ,, between 40 and 45 lbs. per cubic foot. 
54 „ „ 45 „ 50 „ 
14 ,, ,, 50 ,, 55 ,, ,, ,, 
The average weight is rather less than it was twenty 
years ago. 
Shortleaf Pine (P. echinata), also called slash pine, 
Carolina pine, yellow pine, etc., resembles loblolly ; it is 
the common tree of Missouri and Arkansas, and is found 
in all the southern States ; it attains a height of 40 to 
80 ft., and as a timber it ranks next to longleaf pine, 
although as regards strength it is slightly weaker than 
either of the other southern pines. 
Weight about 39 lbs. per cubic foot. 
In appearance the longleaf and shortleaf pine trees, 
particularly the latter, very much resemble the Scotch or 
Northern pine. 
Loblolly Pine (P. tceda) is a large tree which forms exten- 
sive forests in the southern States from Virginia and 
South Carolina right round to Texas. The timber is wider 
ringed, coarser, lighter, softer, and contains much more sap 
than the longleaf pine ; as a rule the larger portion of the 
tree is sap, but the two timbers are sometimes mistaken 
for one another. One occasionally comes across a log of 
loblolly even amongst a lot of good pitch pine, but it can 
generally be detected by its much wider rings, greater
