OURFACE CONDENSERSmdash;Having built and used ?3 at our machine shop and foundry one of J. M Miller's Surface Condensers for the last 14 months, we are now prepared to receive orders for building and putting up said condensers on either high or low pressure engines now in use, and warrant the same against expansion and contraction of the metals, also the injurious effects of oil in the tubes, which alone has caused the failure of condensers heretofore used. We have also found, in the use of our Condenser a nett saving of 30, per cent, of fuel, the water being kept pure and regular in the boiler by the condensation of the steam. In our judgment this Condenser ia the perfecting of the Steam Engine.
