It will sometimes be found requisite to retard the flow of water when
running through soil or other pipes, or to direct it to another
course, or even to form a trap in the length of pipe. This has been
done in many ways, but Figs. 51 and 52 represent the method that I,
after mature consideration, think most preferable. There is nothing
new about this style of bending, as it has been long in vogue with
provincial plumbers, but more especially in Kent. For many years it
has had a run as a sink and slop closet-trap. Mr. Baldwin Latham, in
his "Sanitary Engineering," says it was introduced and has been used
for the Surrey and Kent sewers from about 1848.

I have also noticed many of these traps in the Sanitary Exhibition at
South Kensington, made by Graham and Fleming, plumbers, who deserve a
medal for their perseverance and skill, not only for the excellence of
their bends, but also for some other branches of the trade, such as
joint-wiping, etc., which is unquestionably the best work sent into
this Exhibition--in fact, quite equal to that which was shown at the
Exhibition of 1862. I shall treat further of these bends in an article
on Fixing, in a future part.
