Figure 4 is an illustration of the latest pattern of well adopted.

New Wells.

When a new well is proposed, and local conditions are suitable, a safe form is that designed by Dr. Cameron of Wigton, N. B. This arrangement is shown in Fig. 5. The well should be in the centre of a reserved area of at least 20 yards in diameter, and the lead pipe leading from it to the pump must be fitted by brass screw joinings. This is a suitable design for the vicinity of cutcherries, where an open space for a reserved area is generally available.

Another excellent design for a new well, and one more generally suitable, is shown in Fig. 6. This prevents any danger of the water being contaminated by dirty vessels being lowered into it for the purpose of drawing water.

FIG. 7.

Tube Wells.

Tube wells answer admirably in many localities; it is, however, always essential to have a bore hole made first to determine the stratum which has to be tapped, as the point of the tube may be easily driven through this. An improved form of pump is shown in Fig. 7; this obviates the danger of impure water being put in the mouth of the pitcher spout pump in order to make it draw.
