MATERIAL TESTED. 
The material for test was selected from regular stock, in the form 
of sticks 8 inches by 16 inches in section and from 28 to 32 feet in 
length. The sticks were sorted in pairs, with the object of having 
those in each pair as alike as possible. At the time of treatment 
each stick was cut into two stringers of equal length, making four 
test strangers in each group, two butt cuts and two second or top 
cuts. The groups were handled as shown in figure 1, the butt ends in 
one group being treated and the top ends in the next. 
LONGLEAF AND LOBLOLLY PIXE. 
The longleaf and loblolly pine timber were cut in southern Missis- 
sippi and Louisiana. About five months elapsed between the time

the logs were sawed and the time of treatment, during four months 
of which the pieces were seasoned in an open pile. The treated 
stringers were en route to Lafayette, Ind., for over a month. Upon 
arrival they were close piled under shelter until the tests were started 
about a month later. The pieces as selected were 8 inches by 16 
inches in section by 28 feet long. The material classed as "long- 
leaf" was high-grade timber, considered as first-class structural 
material by the railway officials, and that classed as "loblolly" as 
less valuable. The longleaf had only a small per cent of sap and 
was of comparatively slow growth, while the loblolly averaged over 
30 per cent sapwood, was of more rapid growth, and contained more 
knots. The number of test stringers 14 feet long was as follows:
