They shall also inspect the boilers of such steamers before flw b¤Bg°¤· the same shall be used, and once in every year thereafter, subjecting them to n. hydrostatic pressure, the limit to which, not exceeding one hundred and sixty-five pounds to the square inch for high pressure boi1— ers, may be prescribed by the owner or the master, and shall satisfy themselves by examination and experimental trials, thm; the boilers are well made of good and suitable material ; that the openings for the passage of water and steam respectively, and all pipes and tubes exposed to heat are of proper dimensions, and free from obstruction; that the spaces between the ilues are sufficient, and that the hre line of the furnace is below the prescribed water-line of the boilers; and that such boilers and the machinery and the appurtenances may be safely employed in the service proposed in the written application, without peril to life; and shall also satisfy themselves that the safety-valves are of suitable dimensions, sufficienf. in number, well arranged, and in good One or cus working order, (one of which may, if necessary in the opinion of the in- or we nevigewr. of gauge-cocks properly inserted, and a suitable water-gauge and steamgauge indicating the height of the water and the pressure of the steam; that in or upon the outside flue of each outside high-pressure boiler, there is placed in a. suitable manner alloyed metals, fusible by the heat of the boiler when raised to the highest working pressure allowed, and that in or upon the top of the ilues of all other high-pressure boilers in the steamer, such alloyed metals are placed, as aforesaid, fusing at ten pounds greater pressure than said metals on the outside boilers, thereby, in each case, letting steam escape; and that adequate and certain provision is made for am ample supply of water to feed the boilers et all times, whether such vessel is in motion or not; so thats, in high-pressure boilers, the water shall not be less than four inches proviso M to above the flue: Provided, however, in steamers hereafter supplied with funible plugs- new higlrpressure boilers, if the alloy fuses on the outer boilers at a pressure of ten pounds exceeding the working pressure allowed, and at twenty pounds above said pressure on the inner boilers, it shell be n sufficient compliance with this act.
