ested on the bottom of the tank and the other
end of the tray was raised about 8 inches. Thus
the floor of each tray was inclined so that the
water would drain off. The trays were installed
in such manner that they could be lowered into
water in the tanks whenever it was desired to
take insulation readings or make high-potential
tests. The tanks were known as tank No. 1 and
tank No. 2. The samples in tank No. 1 were
treated with solution No. 1 and the samples in
tank No. 2 were treated with solution No. 2.
Beginning January 7, 1911, the samples were
treated daily with the proper solution, and once
every month or 6 weeks readings were taken of
the insulation resistance of each sample. The
solutions were applied to the insulation of the
conductors by sprinkling from an ordinary watering
pot. For the first 4 weeks the sprinklingwas
done three times daily, for the next 10 weeks
the sprinkling was done once daily, for the next
76 weeks the sprinkling was done
TWICE EACH DAY,
and for the rest of the time the sprinkling was
done once each day. The amount of solution
applied at any one time was approximately 0.17
ounce for each linear foot of conductor. In addition
to sprinkling, aspirator bottles were arranged
so that the solutions could drip slowly
upon certain conductors, thereby maintaining a
saturated condition of the insulation at one point.
One sample in each tray was also embedded in
coal dust, in order to simulate a possible underground
condition.
Beginning S months after the tests were first
started, high-potential tests were made upon each
cambric, rubber, and special sample shortly after
the close of the insulation measurements and
before the samples were removed from the water
in their respective tanks. A record was kept of
the temperature*!: of the room in which the testing
tanks were installed, and during the insulation-resistance
readings the temperature of the
water was maintained constant. The trays upon
which the samples were mounted were lowered
into the water in the tanks about 24 hours in
advance of the time at which the resistance read­

Consular Agent Joseph F. Buck, at Bremerhaven,
Germany, has transmitted a detailed report
on the origin, annual receipts, and average
quantity of coal consumed in Bremerhaven and
Geestemunde, with information as to dockage,
lightering, and the securing of provisions and
other articles in demand by visiting vessels. The
report will be loaned on application to the Bureau
of Foreign and Domestic Commerce, Washington,

The Pittsburgh Coal Co. has asked for bids on

30 of them to be for officials of the company.
