Blasco de Garay, su barco de vapor, y el tesorero Rávago

Stuart, in his work on the Steam-engine, says, that the royal Spanish archives record that «Blasco de Garay tried a steam-boat of 209 tons, with tolerable success, before Charles V., at Barcelona, June 17th, 1543. [Rávago], the chancellor, opposed it, and it was laid aside. It consisted of a cauldron of boiling water and a move-able wheel on each side of the ship.» The expense of the experiment was paid by the government, and a present made to Garay.
