REQUIREMENTS.
New Ulm is gradually coming into
its own as a manufacturing and in
dustrial center of more than ordinary
Importance. Every now and then
exacting tests made by disinterested
parties experts of high rank in their
professions prove the superiority Of
the products of local concerns and add
to their popularity.
Best Tile Made Here.
Recently, at the University of Min
nesota, tests on tile submitted by II
different manufacturing plants have
been made under the supervision OF
D. G. Miller, senior drainage engineer.
All tile were put to the test for strength
and absorption, and the tile submitted
by the Saffert-G Gugisberg Cement Con-
struction Company Of ths city, made
from local ingredients, proved to be
among the very best under both tests.
Has Latest Improvements.
George Saffert, manager of the Com
pany, states that the latest develop
ments in all concrete products are
gradation of aggregates, exact amount
of water content in the mix and curing.
These are the three principal factors
in the manufa cture of concrete pro-
ducts and when carefully carried out,
the best uniform results can be OBJ
tained throughout. The local plant
of the Saffert- Gugisberg Company is
equipped with all the latest improve
ments to carry out all these intricate
factors carefully. All of the aggre-
gates are graded into three sizes, and
by means of overhead measuring
hoppers, the well-selected aggregates
are scientifically proportioned and
carried to the mixers, where they be-
come well mixed with Portland cement,
which is drawn from the four big Rib
stone silos erected last spring for
CeulcuG SGOIlIlS puIpOStS.
Experimental Drain Placed.
An experimental drain was placed
in Lyon county the fore part Of October
this year, under the direction OF
George Warren, manager of the Ameri-
can Concrete Pipe Association, for
which concern the New Ulm plant
furnished the tile. Anyone interested
| in these operations or the manufacture
of concrete products by the use of all
of the latest Improvements, is welcome
to investigate the Saffert- Gugisberg
plant and obtain particulars at any
time.
Standard Requirements.
Mr.. Saffert has furnished us the fol.
lowing information in regard to stand.
ard drain tile requirements, and in
forms us that his company's eight-incf
tile, which were eight weeks old whe1
tested at the University, averaged
/ 1903 pounds per lineal foot in strength
and tested 7.3 per cent absorption
under the boiling test, which is con
/ sidered exceedingly good.
The test requirements for .differen
classes Of standard drain tile, minimum
average ordinary supporting strength
| in pounds per lineal foot for tile iron
1 four to Ia inches in diameter, are a
4 follows: Concrete tile, 1, 200 pounds
shale and fire clay tile, 1900 pounds
surface clay tile, ], 200 pounds; for al
). 16-inch tile, 1900 pounds; for all 18
inch tile, 1,4O0 pounds, and for al
20-inch tile, 1 500 pounds.
The maximum average absorptio,
\ by standard boiling test is II, per cen
for concrete tile (all Sizes; nine pc
cent for shale and fire clay tile, and /
!, per cent for surface clay tile. Th
percentage Of absorption is arrived a
4 9|by first weighing the tile when pei
fectly dry; then placing it in boilin
water and allowing it to remain f
! five hours. Upon being removed, tn
6 Isurface water is wiped off and th
L
i tile is weighed again The differene
in weight gives the percentage Of al
sorption,
! Concrete Tile More Popular.
! An Illustration Of the extent Of tl

figures prepared by the county el
gineer Of Lyon county, from whose r
port the following figures are taken:
Minnesota and Iowa drains, know
