to use them. Mention has already been made of one man using a stone for breaking up a frozen cartridge of gelignite; in another case, a newly appointed agent when asked to show the warming pan for thawing explosives containing nitro-glycerine, produced a ladle for melting lead ; while another foreman having a warming pan admitted that he did not know how to use it.
Those having to handle or use explosives would do well to take to heart some of the words of caution issued by the late Major J. P. Cundill, R.A., formerly one of His Majesty's Inspectors of Explosives :
1. The function of an explosive is to explode. Remember this in dealing with them.
2. If an explosive is described as safe under all circumstances, do not treat it as some people treat a big dog and try how much it will stand. Under these circumstances both explosive and dog are apt to bite. Prefer to see the truth of such assertions tested by the manufacturer or his agent rather than by yourself.
3. There is no explosive within my knowledge in practical use which when exploded in a confined space does not give off noxious or deleterious gases.
4. Do not expect the same class of explosive to do every variety of work. Different classes have their different functions, just as a chisel and a gimlet are both useful tools but will not do each other's work.
5. In using an explosive with which special instructions, e.g. (as to thawing dynamite), are issued, it is wiser to read them before an accident happens than to have to refer to them after the accident to see if they are not, after all, issued for some good reason and meant to be studied.*
Steam Boilers.— Very frequent complaints of neglect to examine and report the condition of boilers have had to be made, and in two cases prosecutions were instituted and convictions obtained. It is a very serious matter to neglect the statutory obligations which are certainly not onerous. One thorough examination inside and out, once every 14 months, the report to be preserved for inspection at any time, is all the law requires. Boilers, as they are sometimes placed without cover or protection from the weather, are liable to rapid deterioration and to become a danger to those who have to attend to them; the best course is to insure them with a good Insurance Company, who will undertake to put them through a thorough examination by an expert at least once during the statutory period.
Guard for Slate-dressing Machines.-Mr. Morris Llewelyn Williams, who is a fitter at the Penyrorsedd slate quarry, has invented a neat and effective guard for the Greaves' slatedressing machine. One of the guards has been on trial at the quarry for some time, and is said not to hinder the work, while it certainly adds to the safety of the persons using the machine. The guard, which is shown in Figs. 2 and 3, can be adjusted to any height.

Fossil Remains.—On account of a remarkable find of Reptilian footprints, the Higher Bebington sandstone quarry, at Storeton, Cheshire, has been the resort of a great number of geologists and others interested in science during the year. From time to time, what are known to geologists as Cheirotheroid, Rhynchosauroid, and Chelonoid footprints had been discovered at this quarry, but since the present owner introduced a stone channelling machine, much more work is being done, and the slabs are got out with less breakage. The quarry, which is worked in the Keuper sandstore, has a vertical face of about 130 feet, and at two horizons about half way down the face occur two thin beds of marl on which the interesting footprints are found, and casts of them occur on the · layer of sandstone immediately overlying the marl. Photographs of the face of the quarry and of some of the footprints are reproduced in Figs. 4 and 5.
