So far as inking qualities and finish were concerned, the experi- 
mental papers were entirely satisfactory. Many of the sheets, how- 
ever, had a muddy appearance, particularly when placed beside the 
light-colored all-spruce sheet. It was the opinion of the pressmen 
that, notwithstanding this, most of the sheets were very fair. Those 
which seemed most promising were the balsam sheet (stock 6,) 
which ran very satisfactorily, though light in weight, and in color 
compared favorably with the all-spruce sheet, and stock 9, containing 
374 per cent of hemlock ground wood and 374 per cent of spruce 
ground wood, which compared very favorably in color and printing 
qualities with ordinary news-print paper. Both of the lodgepole 
sheets and the red-fir sheet also had a good color. The tamarack 
sheets (stocks 11 and 12) ran well, but were dark. The following is 
an extract from the St. Louis Republic regarding the trial runs of 
the experimental papers. 
The paper was used to print a part of the issue of the Republic on both Tuesday, 
April 29, and Wednesday, April 30, these trial runs being the first and only efforts so 
_ far made to use the experimental paper in a commercial way. The Republic volun- 
teered to cooperate with the Government laboratory, and is gratified that it can report 
the paper used was of a quality to justify hopeful anticipation that substitute woods 
can be used which will serve to hold a good part of the paper-making industry on 
American soil, * > ~  * 
RESULTS ENCOURAGING. 
As already remarked, the experimental runs developed results that were quite dis- 
tinctly encouraging. These, however, can not be appraised with any measure of 
exactness for several reasons. First of these was the fact that there was not enough of 
any one particular make of paper to enable the pressmen in charge of the Republic’s 
presses to acquire the familiarity that tends to good results. Sixteen rolls were sent 
for trial, and in only three instances were there as many as two rolls of the same par-
