and now and then testing of materials was employed to find the
best methods to secure the most favourable quality of the mate-
rials for the use of the Royal Navy-Yard.
As the more important materials now are imported from
foreign countries we have during the later years turned to follow
the specifications for testing which are used in the navies of the
more important countries and especially the specifications of the
navy of the country which furnishes us with the materials. By
this method a great advantage is obtained both with regard to
economy and to reliable furnishing as the great foreign manu-
factories more easily can procure materials answering to the re-
quirements which are made by a great consumer like the navy
of the country itself than procuring the materials as we — a
comparatively small consumer — want them, according to spe-
cial specifications.
In consequence of this manner of proceeding which on the
whole has proved to be very favourable to the Royal Navy-Yard
there are not during the later years made testing of materials
which may be supposed to be of interest for the members of
the congress.
e. Account of the Tests made by the States Technical Office
for Testing of Paper1).
The States Technical Office is founded in 1888 and has
since then tested the paper used by the government itself but
made no tests for private people. The tests have included the
determination of the paper’s strength, resistance to creasing and
folding , determination of ash and microscopical examinations,
all according to the usual methods.
Further the office has tested ink and the like.
f. Various Other Informations.
Besides tests of materials have been made at several other
places. Thus, with regard to investigations of wood, Mr. E. Hor-
nemann, forest assistant, published in »Tidsskrift for Skovbrug«
(Journal on forestry) V. XI, 1889, »Some investigations on the
