11? ' TRANSACTIONS OF THE 



musical artists. In bis exhibition were also a flute, a violin and a clari- 

 net. 



Goodwin'& Co., of San Francisco, exhibited a splendid assortment of 

 luxurious furniture, comprising bedroom and parlor sets, and a magnifi- 

 cent bridal chair, all of which, for taste and skill, challenged admiration. 



The Oakland Cotton Mills, of Oakland, exhibited forty pieces of 

 cotton cloth from their mills. 



H. Wachhorst, of Sacramento, exhibited a case of splendid gold and 

 silverware, comprising jugs, vases, goblets, card cases, knives, forks and 

 spoons, etc. 



Frank CI. Edwards, of San Francisco, exhibited samples of the first 

 wall paper manufactured in California, upon which was delineated a 

 variety of tropical scenes. 



William H. Jessup & Co., of the Eureka Match Factory, made a fine 

 display of goods in their peculiar line, which were tastefully arranged 

 upon a revolving pyramid, on the pedestal of which stood a wax doll, 

 finely dressed, which was raffled off for the benefit of the orphans. 



The North American Wood Preserving Company presented specimens 

 of wood preserved by a peculiar process, by which it is claimed that the 

 end is gained of rendering the wood proof against dry and wet rot. and 

 impervious to the attacks of the toredo and all marine insects, while the 

 fibre of the wood remains intact and is in no manner impaired. The 

 many advantageous uses to which this wood thus prepared can be put 

 will naturally occur to the reader — such as the construction of wharves, 

 foundations of buildings, and pavements, etc. 



Jones & Peterson, of Antioch. Contra Costa County, exhibited in the 

 shed adjoining the Pavilion a patent spring hammer, which dispenses 

 with the necessity of employing a striker. It is operated by a treadle 

 passing along on the right of the anvil, and the blow can be governed 

 with as much accuracy as by hand, while the hammer can be moved 

 to any part of the anvil. The hammer strikes a very powerful blow 

 with the exercise of very little muscular power. 



H. B. Martin & Co., of San Francisco, exhibited a patent oscillating 

 double cylinder steam engine of four horse power, which occupies a 

 compass of three feet by ten inches. The pcculiaritj- of this engine con- 

 sists in the fact that the steam chest and slide valves of the ordinary 

 engine are dispensed with. The steam is admitted into a plug running 

 crosswise through the cylinder. The plug is cast solid in the centre, 

 and when it is receiving steam on one side it is exhausting it on the 

 other, and it requires but the oscillation of the cylinder to reverse the 

 position of the plug, and admit steam to the opposite piston. The 

 motion of the engine can be revei*sed by the turning of the plug, by 

 means of a lever, without shutting off steam. There is no connecting 

 rod, the piston being attached directly to the crank. It is claimed that 

 it does not require a practical engineer to operate this machine. They 

 also exhibited a hydrostatic engine, on the model of the steam engine 

 above described, with the exception that one is steam and the other 

 water packed ; a pump, on the principle of the engines above described, 

 for irrigating, railroad or family use ; and a rotary pump, for deep wells 

 or mines, which is constructed without valves, and is claimed to possess 

 sufficient capacity to force water three hundred feet. These are Cali- 

 fornia inventions. 



A. C. Taylor, of San Francisco, exhibited a new portable range, the 

 oven doors and outer flue plates of which are filled with cement, which 

 being a non-conductor of heat, retains the caloric and makes the oven to
