Instruments used in Cave-hunting.
The instruments which Mr. James Parker, Mr. Ayshford Sanford and myself have found most valuable in cave-hunting, apart from the tools of the workman, are as follow:—
1. A hammer with an ash handle about twenty inches long, inserted into a square head of best steel, ending in a chisel edge in the same plane as the handle, weighing almost eight ounces, and seven inches in length.
2. A steel chisel ten inches long.
3. A prismatic compass.
4. A thermometer for taking the temperatures of the air and water.
