r. The wiping
cloths should receive a little more oil to keep them soft and
pliable. Oil the edges of the cloths well.

SUPPORTING.--To support this pipe for wiping have each end rest on
a brick. Each end can be weighted to hold it in place.

WIPING.--To wipe this joint, proceed to drop the solder on the
joint. When the pipe is thoroughly heated and the solder works
freely around the pipe the joint can be wiped. The procedure is
like the preceding one. The wiper is cautioned to move the ladle
constantly while dropping the solder.

BRANCH HELD VERTICAL

After a number of the previous joints have been wiped successfully,
the pipe is placed in such a position that the branch will be
vertical. The supporting of the pipe to hold the joint in this
position for wiping is very easily done after handling the 5/8-in.
joint in this position. The following points may be found helpful:
The solder is splashed on the joint from the ladle. The top edge of
the joint is kept hot by keeping the solder covering it. When the
proper heat has been got up, the top edge is wiped first, then the
bottom edges both front and back. The body of the joint is wiped
last and a cross wipe finishes the joint. I have found that the
beginner in many cases, when this joint is reached, tries to wipe
it with many short strokes. The habit is a bad one and should be
stopped as soon as noticed. Learn to wipe the top edge with only
two strokes, the bottom edge with not more than four, the body of
the joint with four, and one cross wipe to finish. This joint
should be finished as symmetrically as possible and wiped while the
solder is hot.

RUN HELD VERTICALLY

When the vertical branch has been conquered and the wiper can get a
good joint every time it is tried, the pipe can be changed to a
different position. The run is placed in a vertical position and
the branch horizontally to the left. The catch pan is put under the
end of the pipe. Follow the same directions for supporting this
joint as were given under the 5/8-in. branch placed in a similar
position. The wiping of this joint is so nearly like the preceding
branch joints that I will not give any instructions at all. This
joint is finished at the same point that the other branch joints
are finished. However, there are one or two matters that should be
kept in mind. Some of the small matters are often overlooked and
should be called to mind occasionally. Do not allow the solder to
accumulate in t
