▲ A MS. addition to Mr. Heber's copy of lord Worcester's book contains the following description of this grand hydraulic machine; ascribed, by the enthusiastic contriver, to celestial inspiration.

"A stupendious or a water-commanding engine; boundless for height or quantity, requiring no external nor even additional help or force, to be set or continued in motion, but what intrinsically is afforded from its own operation, nor yet the twentieth part thereof: and the engine consisteth of the following particulars.

"1. A perfect counterpoise for what quantity soever of

water.

"2. A perfect countervail for what height soever it is to be brought unto.

"3. A primum mobile, commanding both height and quantity, regulator-wise.

"4. A vicegerent or countervail, supplying the place and performing the full force of man, wind, beast, or mill.

"5. A helm or stern, with bitt and reins, wherewith any child may guide, order, and controul the whole operation.

"6. A particular magazine for water, according to the intended quantity or height of water.

❝7. An aquaduct, capable of any intended quantity or height of water.

"8. A place for the original fountain or even river to run into, and naturally of its own accord incorporate itself with the rising water, and at the very bottom of the same aquaduct, though never so big or high. "By

debts being paid, and a competency to live according to my birth and quality setled, the rest shall I dedicate to the service of our king and country by your disposals. And esteem me not the more, or rather any more, by what is past, but what's to come; professing really from my heart, that my intentions are to out-go the six or seven hundred thousand pounds already sacrificed, if countenanced and encouraged by you; ingenuously confessing that the melancholy which hath lately seized upon me (the cause whereof none of you but may easily guess) hath, I dare say,

"By Divine Providence and heavenly inspiration, this is my stupendious water-commanding engine, boundless for height and quantity.

"Whosoever is master of weight, is master of force; "Whosoever is master of water, is master of both :

"And consequently to him, all forceable actions and atchievements are easie, which are in any wise beneficial to, or for mankind.

"The treasures buried under these heads, both for war, peace, and pleasure, being inexhaustible; I beseech you pardon if I say so; it seems a vanity, but comprehends a truth; since no good spring but becomes the more plentiful by how much more it is drawn, and the spinner to weave his web is never stinted, but further inforc'd.
