The only disadvantage in viewing the work as we have, is that the bath room fixtures on the other side of the house come directly behind those shown in our drawing, and therefore cannot be represented. In this case, however, it is not essential that more than one of the two sets of fixtures should be shown, for the two are exactly alike, and no additional benefit is to be derived from showing the rest of this work. The connection of the bath room stack into the main drain in the cellar is shown enlarged in Fig. 86. As in the case of the toilet room stack of our last article the location of the bath Toilet Cleanout Room Stack main Drain Enlarged Detail of Correction at Foot of Toilet Room Stack Fig .86.

In the case of Fig. 85, the horizontal line runs so close up to the cellar wall that there is no chance to use an end cleanout, and a horizontal cleanout must be used. As so often happens in an architect's plans, this cleanout has not been shown on the cellar plan, as it should be. This simply shows that wherever detail drawings are given they should be given full attention. Concerning Fig. 86, all there is to be said is that this foot connection cannot be shown on a cellar plan with any degree of clearness, and it is necessary either to give a detail or to show the connection on the respective elevations. Regarding Fig. 87, it will be seen on referring to the cellar plan, Fig. 78 of the preceding article, that on this plan the fresh air inlet would show directly above the main drain, and therefore to show clearly an elevation of this part of the work must be given. It will be good practice for the student to work out all the work shown in this chapter. Fig. 84 can be shown twice as large as given, but the remaining sketches can be drawn up in the same size as we present them. We might add here, that in working up his drawings, the student would do well to practice lettering, following the style of lettering used on our illustrations, for it is a fact that a man may make a finelooking drawing and spoil its entire appearance by poor lettering. Side View F OR the work on this chapter and the one following, we propose to take up the plumbing of a residence, and show it in full, believing as we do, that this branch of the work is fully as important to the plumber as any that we have taken up. For this purpose we show a full set of plans for such a residence, Fig. 1 representing the cellar plan, Figs. 2 and 3 and 4 the floor plans, and Fig. 5 the front view or elevation. In this and the following chapter we shall show separate elevations of the different stacks, in each case taking these IST. FLOOR PLAN views from the most advantageous point of view, and before leaving the subject of the plumbing for this residence, we shall show a single elevation of the entire work of the house, taken from one view point. Now in Fig. 6 we show an elevation of the work in the kitchen on the first floor, and the laundry in the cellar. These fixtures are so located that they can be shown to advantage in the one view, which is obtained by viewing the work from the direction of the arrow E, which appears on both cellar and first floor plan. Instead of using up valuable space in showing floors above the first floor, and |
