5. String, sealing-wax, and writing paper gummed on one side, for labels to affix to specimens on the spot.
Lign. 266. Geological and Mineralogical Hammers.
| Fig. | 1. and 4, 6, are adapted for breaking large stones or masses of hard rock; the thinner ends are convenient for splitting and trimming fragments to a moderate size. The head should be from four to five inches long, one and a half inch wide on the crown, and from two to three pounds in weight; the length of the handle from eighteen to twenty inches. |
2 and 3.—This is my favourite hammer, and will be found most generally useful; the short square head for breaking, and the pick for splitting stones, and extracting fossils of moderate size; weight of the head two pounds, length seven inches; width of the crown one and a half inch; handle from twelve to fourteen inches long, and one inch wide at the lower part, for the convenience of a firm hold. If the handle be graduated as a foot measure, as in fig. 5, it will be found useful.[782] | |
5 and 8, 7, are smaller hammers for breaking and chipping stones and minerals; the heads from three to four inches long, and one and a half pound in weight; the handle one foot long. |
[782] Hammers of this kind may be obtained at Messrs. Knight’s, Foster-lane, London; and at 49, Cockspur-street, Charing Cross: care should be taken that the heads are of well-tempered steel, and the handles of tough wood.
6. A strong pair of gloves, and a pair of eye preservers; common spectacle frames covered with fine black crape will be more agreeable than glass.
7. A measuring tape, a pocket compass, and drawing materials will be required, if the observer intend to note the geological characters of the district.[783]
