Lever Buchet Mach'me.

[Book I.

pressure of the arm C E on the end I. The bücket D when empty, hasits mouth upwards, being suspended as above mentioned. The end Dwith its bücket is also lighter than the end with the bücket E, when bothare empty. By reason of the different bore of the spouts, D is filled al-most as soon as E, and immediately preponderating, sinks down to D,and thereby raises the contrary end of the lever and its buckelup to the cistern M, into which it discharges its water; but immediatelythe bücket D becoming full, pours out its water, and the end of the leverE comes down again into its horizontal Situation, and striking upon theend I of the loaded lever I K, raises the weight K, by which means theforce of its blow is broken. If the distance A B or fall of the water beabout six feet, this machine will raise the water into the cistern M twenty-four feet high. Such a machine is very simple and may be made in anyproportion according to the fall of the water, the quantity allowed to bewasted, and the height to which the water must be raised.”

“ Some years ago,” Dr. Desaguliers continues, “ a gentleman showed mea model of such an engine varying something from this, but so con-trived as to stop the running of the water at A A, when the lever D Ebegan to move.

There is a singulär historical fact connected with the use of buckets toraise water from Wells , which will serve to conclude this part of the sub-ject. Every person knows, that war between nations has often arisenfrom the most trifling causes; when thousands of human beings, alikeignorant and innocent of its origin, hired by its authors, armed withmurderous weapons and incessantly exercised in the use of them, aremarshaled into the presence of a similar host; when both being stimu-lated by inflaming addresses, and often e.xcited by ,ardent spirits, destroyeach other like infuriated tigers! Then after one party is overcome, theother glorying in the slaughter, hail their leader a Tiero, and not infre-quently do that, which fiends would shudder to think of—viz. returnthanks to the benign Savior of men, for having enabled them thus to de-
