stacks in Fig. 129, measure to the left of the wall a distance equal to the distance on the cellar plan from the foundation to the center of the main drain.

We show simply a single line to designate the length of the soil pipe risers. If those of our readers who are not used to scaling drawings will figure out the distance in feet between the several floors and the depth of floor beams, it will be good practice for them, and this might be done also with the cellar plan.

In Fig. 130 we give two simple sketches of the two stacks shown on the cellar and floor plans. The same scale that has been used on these plans is used on the elevations of the two stacks, as far as heights between floors, etc., is concerned, but the diameter of the pipe, length of fittings, etc., is not drawn to this scale; in fact, not to any scale.

It can readily be seen that if this scale were followed on the piping the diameter of the 4-inch pipe would appear on our drawing as only 1-24-inch, which would be too small to show well. It will usually be found almost impossible to adhere to the scale on the piping for the reason just given.

We would advise the reader as excellent practice work, to work out the several floor plans on some scale larger than that which we have followed, completing fully the twc floor plans which we have shown only partially complete, and also completing the work on the elevations of Fig. 130, by showing the fixtures and all their connections.

that as a general thing, work in the country is not done under the regulations of a plumbing ordinance, and for that reason in a majority of cases the work is put in without venting, though the country resident is gradually being convinced that he should have as good and as sanitary work in his house as his city brother.

Acknowledging that work of this kind has to be done, we show this plumbing system invented, and as a precaution against syphonage, show drum traps under the fixtures instead of the ordinary strap, which is more susceptible to syphonage.

On such work, the style of trap shown, or one of the modern anti-syphon traps, we believe far preferable to the S trap.

It will be noticed that in accordance with Fig. 134, our elevation shows the well located above the cesspool, which

should be demanded in order to lessen the danger of leeching of the contents of the cesspool into the well.

In Fig. 136 we give another elevation, showing the water supply for the house with windmill pumping to the storage tank.

This and the drainage system elevation are generally combined in one drawing, but on such a small scale greater clearness is obtained by keeping them separate.

Thus far in this series we have done more work in connection with the drainage end of plumbing than with the water

supply, though both are equally important.

This needs attention before we bring our series to an end, and will therefore next claim our attention.

It will be a good plan for those interested, to work out the two elevations which appear in this article, using, however, a much larger scale, for the use of a small scale makes this work of such a puttering nature that it becomes very tiring, and furthermore, a larger scale would allow of showing small details, such as fittings, wiped joints, etc., and these little points go a long way to make an attractive drawing.
