[Fig. 206]. Tongs for lifting stones. The pull on the shackle which connects the two links causes the latter so to act on the upper arms of the tongs as to make their points press themselves against or into the stone. The greater the weight, the harder the tongs bite.

THE WEATHER AND INDOOR WORK
The measure of rainfall varies considerably within comparatively small areas, and this renders it no easy matter to get correct figures, so that the nearest records are those taken from a number of gauges within a limited district, and generalized. The more this is done, the less will be the inaccuracy in referring to the rainfall of any particular district or country.
Fig. 207. Rain-gauge
If numerous rain-gauges were established throughout the country, and all their records sent to one central station, what valuable information might be collected for a particular district or country in the course of years. Means might be found for using the superabundant water, which falls in one part over another part, where the rainfall is less. Information such as this might be of special value in the West and South. It is collected now to a certain extent; but not done so generally as it ought to be.
