Will always start when the steam cylinder is filled with cold water of conensation. The trial of Steam Pumps at the Eighth Industrial Fair in San Francisco, by a Committee of Five of the most thoroughly practical mechanics on this coast, showed the Knowles Pump to lose but 1124 per cent., while others lost as high as 40 per cent., showing great difference in economy.
