The bearings appear to be worn ex-
cessively. The leaking through the
timing gear case may be due to oil
getting into II through the front main
bearing. Much Oil may be lost by
leaking through the rear bearing.
Kindly explain how a storage battery

90. What kind Of acid should il take7
A lead storage battery consists es-
sentially Of a number of lead plates,
each cast In the form Of q grid. and a
glass container. The spaces in the
plates are filed sgith oxide OF lead In
the case Of the positive plates and
spongy or finely divided lead In the
case of the negative. In the construc-
ton OF your battery two OF the plates
will act as positive and two as mega
tive. The plates should have means
for making suitable connection. and
usually this connection Is made. The
glass jar which holds the plates should
be Of sufficient size TO accommodate
the plates and the solution. On the
bottom OF the ~container two treated
wood blocks are placed, these being
used to support the plates. The plates
are set upon the blocks so that the
negative plate faces a positive plate.
Between each two plates are treated
wood separators. You will have to
buy these of some storage battery com
pany, or you might try some good
grade Of porous wood or hard rubber
drilled with small holes. These sep
arators have a small end section area.
but are as long as the plates them
selves. Separators Of one-half by one
fourth inch section will do. With the
plates In position connection Is made
between the two positive plates and
between the two negative and the ter
minals from each set brought out to
be attached to Tugs. These Tugs are
attached to a hard rubber cover for
the container. The cover should be
about three-fourth inch above the tops
Of the plates. After the plates have
been connected to the Jugs and the
cover is In position molten tar should
be poured all over the cover and tar
around the Tugs, so as completely to
seal the Jar. After the tar has become
hard dilute %sulphuric acid of specific
gravity of one and twenty-eight hun
dredths. This should be poured
through the hole In the cover and
enough poured into the Jar to COM
pletely cover the tops Of the plates.

How can oil be stopped from leaking

Do not put too much lubricant into
the case. for this will cause excessive
gassing and thus push the oil our
