do not stand so that their full shape appears, but as shown in Fig. 8. While strictly adhering as a general thing to the exact appearance of an object of this nature in our work, it will often be found of advantage to depart from this rule, and in such a case as this, to show the shape of the trap. Instead of showing the two bath rooms on the second and third floors in one elevation, we show each separately in Figs. 9 and 10. This is done simply to save space.

The third floor or servants' bath room is viewed along the direction of arrow M in Fig. 4, which gives us a very clear view of the work. In this view the main back air line stands in front of the main stack, and we attach a note showing where the connection of the former with the latter may be found.

In the same way we show a note on Fig. 5 indicating where the upper connection between these two lines of pipe may be seen. As this shows, & note of this kind may often take the place of the drawing itself. The view shown by Fig. 10 is taken along arrow

The elevation of the house shown in Fig. 14 shows by the letters A and B just how high up on the roof the two stacks come through, and by the letters C, D, E, and F the several floors.

Such work as this, we believe, will be of the greatest benefit to any man following this series, and we believe that if he has followed carefully what has gone before, in the preceding chapters, he can handle the work without much difficulty.
