FORGING A PROPELLER SHAFT.

During the recent visit of the Shah of Persia to England, he visited,

among other places, the great works of John Brown & Co., at Sheffield,

and witnessed the pressing of a propeller shaft for one of the large

ocean steamships. The operation is admirably illustrated in our

engraving, for which we are indebted to the _Illustrated London News_.
