      (1.) What limits the speed at which the reciprocating parts of machines may act?(2.) What is the nature of reciprocal motion produced by cranks?(3.) Can reciprocating movement be uniform in such [108] machines as power-hammers, saws, or pumps?(4.) What effect as to the rate of movement is produced by the elastic connections of a trip-hammer?

      On Thursday, August 20th, I decided to go once more in the direction of Tongres. As the Germans had picketed the main road along the Netherland frontier, I made a detour and dragged my bicycle across the mountain near Petit Laney, a very trying job in the stifling heat. From the mountain top I had a beautiful vista, which enabled me to see that near Riemst a large German force was encamped at which I desired to have a look. So I walked down the hill to Canne, where some crofters were trying to get their cattle into The Netherlands. These poor creatures, who usually own two or three head of cattle, had been compelled already to give up half of their stock. From Canne I cut through corn and beetroot fields to the road to Riemst. The first German sentinels were tolerably friendly."Yes, all right, you may go, but we only want you to tell us what you know of this man."

      43 "Oh! Bart, is it you?"

      "All right, sir."

      I think proper to point out these peculiarities, not so much from any importance they may have in themselves, but to suggest critical investigation, and to dissipate any preconceived opinions of forging being a simple matter, easy to learn, and involving only commonplace operations.


      By placing the axes of tangent gearing so that the threads or teeth of the pinions are parallel to the face of the driven teeth, [53] as in the planing machines of Messrs Wm. Sellers & Co., the conditions of operation are changed, and an interesting problem arises. The progressive or forward movement of the pinion teeth may be equal to the sliding movement between the surfaces; and an equally novel result is, that the sliding action is distributed over the whole breadth of the driven teeth.


      [164]"Oh no! That is impossible, and, after all, we are not afraid of Japan either. You had better write in your paper that we are not afraid of anything excepting Montenegro. And you may also inform your readers that it is better for Netherlanders not to cross the frontier, as we are going to apply much stricter measures. For we have evidence that those people from Vis and other106 villages who fled to The Netherlands are returning with forged papers, in order to shoot at us. And now you may go, but back to Maastricht at once."


      Inventions in machine improvement, no matter what their nature, must of course consist in and conform to certain fixed modes of operating, and no plan of urging the truth of a proposition is so common, even with a chance inventor, as to trace out the 'principles' which govern his discovery.
