For pumping out mines or pumping water in any way, this is considered by miners and engineers as superior to anything now inuse. Parties on this coast now using them will attest to their efficiency. HOUSE FRONT CASTINGS. We claim to make the best castings of the above kind of work now made on the Pacific coast, and think that a reference to our work will bear us out in the assertion. We would call the attention of the public to the following Iron Fronts made by us Fireman’s Fund Insurance Building; San Francisco Sayings Union; the New California Market; Chas.

DUNBAR’S SELF-ADJUSTING STEAM PISTON PACKING. The accompanying and following are some of the specialties of the work of this Establishment : DUNBAR’S PATENT? PISTON PACKING, WITH SMITH’S IMPROVEMENT, There are of this Patent upwards of rHrEe HUNDRED in actual operation on this coast.

It is designed for hoisting purposes generally, and is just We should not then hear of the mining accidents which occur the thing for miners. daily from the giving away of hoisting gears. Parties using them in stores in this city give some of the best kind of certificates of their value over any other kind of Friction Hoist. W. W, HANSCOM’S IMPROVED DIRECT-ACTING STEAM PUMP, Being made of only five pieces of metal, and having only two movable parts, it is considered by experts to be the simplest and best feed Pump ever yet invented. CARVALHO'S PATENT STEAM SUPERHEATER A very valuable invention for economy of steam, suitable for all purposes of heating and drying steam. Recommendations from parties using them in this State can be had on application. BEMIS’ PATENT GRATE BAR, For burning screenings and fine coal, soft orhard. This isa very valuable invention, and has done more for the benefit of California coal mines than anything else. By the use of this Grate Bar, all the debris and screenings can be used which formerly had to be thrown away. It is in use in about all the steamers on this coast and for many land boilers. All parties using coal will find it to their advantage to use these Bars. ORNAMENTAL CASTINGS. We have established a special department for Ornamental Work, Stove Plate, Piano Plates, and all kinds of Fancy Castings, to which public attention is respectfully called. All of the above mentioned articlesewill be on exhibition at the Mechanics’ Sixth Industrial Fair, and the attention of the public is respectfully called to the merits of each article as set forth.
