e procured. If gasoline is to be used
for fuel to heat the solder, make sure that the tank is full before
starting, otherwise the fire may go out just when the heat is
needed most and the solder in the pot has become too cool to wipe
with. Have a catch pan and keep all the solder droppings to put
back into the pot, otherwise the solder will pile up and the
fingers are likely to be pushed into the pile and badly burned.
Hold the ladle about 2 inches above the work, the catch cloth
about 1 inches below. Do not drop the solder in the same place.
Keep moving the ladle. Do not pour the solder on the pipe in a
steady stream, but drop it on. It is not a large amount of solder
that is wanted on the joint at first, it is heat that is needed.
This can be secured better by dropping the solder on than by
pouring a large quantity on the pipe. The edges of the joint cool
very quickly; therefore heat the edges well and keep them covered
with molten solder until the joint is ready to wipe. When preparing
joints for wiping, always do the work thoroughly and fit the pieces
together tightly so that no solder can get through.

_Seventh_, cloth 1 inches below the work.

_Eighth_, move the ladle continually.

_Ninth_, _drop_ the solder.

_Tenth_, _heat_, not solder wanted at first.

_Eleventh_, heat the edges.

HALF-INCH ROUND WIPED JOINT

PREPARATION.--Take 12 inches of 1/2-inch strong lead pipe and
square off the ends with a rasp. Take the shave hook and scrape the
center of the pipe perfectly bright; a space 3 inches each side of
the center is correct. The size of the joint when completed should
be 2-1/2 inches long. If we should undertake to wipe the joint
with the pipe in the present condition, the solder would adhere to
all the pipe that was shaved bright. Therefore, we take a piece of
paper sufficient to encircle the pipe twice and after putting paste
on one side of the paper wrap it around the pipe so that the edge
that is cut straight and even is 1-1/4 inches from the center of
the pipe. Another piece of paper is pasted on the oth
