Bellows Forcing Pumps.

A plain within th Areadian land I know,

Where double winds vvith forced exertion biow,

Where form to form with mutual strength replies,

And ill by other ills supported lies;

That earth contains the great Atrides son;

Take him and conquer : Tegea then is won.

On the receipt of this, search was again made for the body without inter-mission, and at last it was discovered in a singulär manner. At the time acommercial intercourse existed between the two countries, a Spartan cav-alry officer, named Lichas, being in Tegea, happened to visit a smith athisfbrge, and observing with particular curiosity the process of working theiron, the smith desisted from his labor and addressed him thus: Strangerof Sparta, you seern to admire the art which you contemplate; but howmuch more would your wonder be excited, if you knew all that I am ableto communicate! Near this place, as I was sinking a well, I found acoffin seven cubits long. I never believed that men were formerly oflarger dimensions tban at present, but when I opened it, I discovered abody equal in length to the coffin1 correctly measured it, and placed itwhere I found it. Lichas, after hearing this relation, was induced tobelieve that this might be the body of Orestes , concerning which theOracle had spoken. He was further persuaded, when he recollectedthat the bellows of the smith might intimate the two winds; the anvil andthe hammer might express one form opposing another; the iron also,which was beaten, might signify ill succeeding ill, rightly conceiving thatthe use of iron operated to the injury of mankind. The result provedthe sagacity of the Spartan: the body was recovered, and finally theTegeans, says Herodotus , were conquered. Clio, 67, 68.

No. 107. Single Forcing Pump.

No. 106. Double Lantern Bellows Pump.

The application of lantern bellows as forcing pumps is, without doubt,of great antiquity : their adaptation to raise water was too obvious not tohave been early perceived, and hence we infer that they were at least oc-casionally employed for that purpose by most of the nations of old. Suchpumps are mentioned in old works on hydraulics ; but as they bave never
