I had given a glass ball to the wife of a friend, whose visions proved so startling and on one occasion so unholy that she ceased to make experiments. One day my friend's secretary, a young student and golfer, took up the ball. "I see a fie... Read more of The Cow With The Bell at Scary Stories.caInformational Site Network Informational

The Forging Of Steel






Category: THE FORGING OF STEEL

So much depends upon the forging of steel that this operation must
be carefully supervised. This is especially true because of the
tendency to place unskilled and ignorant men as furnace-tenders
and hammer men. The main points to be supervised are the slow and
careful heating to the proper temperature; forging must be continued
at a proper rate to the correct temperature. The bar of stock from
which a forging was made may have had a fairly good structure, but
if the details of the working are not carefully watched, a seamy,
split article of no value may easily result.
