There is a problem as to the principle of action in a Barker wheel, which although it may be very clear in a scientific sense, remains a puzzle to the minds of many who are well versed in mechanics, some contending that the power is directly from pressure, others that it is from the dynamic effect due to reaction. It is one of the problems so difficult to determine by ordinary standards, that it serves as a matter of endless debate between those who hold different views; and considering the advantage usually derived from such controversies, perhaps the best manner of disposing of the problem here is to state the two sides as clearly as possible, and leave the reader to determine for himself which he thinks right.CHAPTER XXXII. TOUCH AND GO.
"Yes, Captain." As I wiped the brow again I heard the tread of two horses down in front of the house; they were Gholson's, and Ned Ferry's for Charlotte. "Captain, may I go and bring her--tell her what you say, and bring her?"
Gregg passed the hat and wig to Allingham, and whispered something. The other looked at the inside of the hat. There was a small label in the centre, with the following matter printed upon it:"When we came in sight of Canton, we saw some buildings that rose far above all others, and very naturally we asked what they were. We were somewhat taken aback when told that they were pawnbrokers' establishments, and of course they were among the things we went to look at. They were filled from top to bottom with clothing and other things, and our guide explained to us that the Chinese are in the habit of pawning everything they are not using, for the double reason that they get money which they can use, and at the same time they save the trouble of taking care of the property. At the beginning of winter they pawn their summer clothes, and at the beginning of summer they pawn their winter clothes. All other things on which they can borrow money they take to the pawn-shop, even when they are not obliged to have the cash. It saves the trouble of storing the goods themselves, and running the risk of having them stolen.
"There will be an accident," retorted Allingham. "Mark my words, he won't get very far."The Clockwork man shook his head slowly from side to side. "No children. No lovenothing but going on for ever, spinning in infinite space and knowledge."
The two of us sprang forward. How long or what way we went I have now no clear idea, but at length we neared again the grapevine ferry. The stream was swollen, we swam our horses, and on the farther side we found Kendall waiting. To the corporal's inquiry he replied that Ferry had just passed on. "You know Roy's; two miles off the Plank Road by the first right? He expects to stop there."
A learner will no doubt wonder why sand is used for moulding, instead of some more adhesive material like clay. If he is not too fastidious for the experiment, and will apply a lump of damp moulding sand to his mouth and blow his breath through the mass, the query will be solved. If it were not for the porous nature of sand-moulds they would be blown to pieces as soon as the hot metal entered them; not only because of the mechanical expansion of the gas, but often from explosion by combustion. Gas jets from moulds, as may be seen at any time when castings are poured, will take fire and burn the same as illuminating gas.
