ON THE IRRIGATION OF RICE LANDS BY 

 PUMPS. 



From tlie Southern Agriculturist. 

 I have been desirous to obtain some maciiine to 

 irrigate rice lands; in furtherance of this objert I 

 wrote 10 JMr. J. Rearc, Pall Mall Kast, London, 

 the inventor of a pump, said to combine many 

 advaniages. I propounded several questions con- 

 cerning his pump, and I enclose you his reply. 

 Some rice planters are situated on rivers, lUat in 

 dry seasons become loo salt at high water, to 

 flow the land with, but which are fresh from half 

 ebb 10 half flood tide. An efficient pumping ap- 

 paratus would render lands in such situations as 

 safe to plant, as those not having the evil of s^lt 

 water to contend with. Inland swamps too miuht 

 he drained or flowed at vvill. The only objection 

 I see to the pump, (taking Mr. Beare's replies to 

 be correct, which 1 do not doubt,) is the price. 

 The quantity of water lifted per minute, would 

 flow an acre six inches deep in Iwenty-lbur and a 

 half minutes. If you could obtain any funh'-r 

 information on this subject, you would pet;hai)« 

 benefit a number of rice planters by publishing it, 

 at any rate you would bne oi' your 



Subscribers.

Sir — 1 have the favor of your letter under date, 

 Savannah, (Geo.,) 15ih May last, acquainting me 

 that Capt. T. Baylis, of the British K. I. Army, 

 has conveyed lo you an opinion, that my new 

 plan, or new principle in pumps, must be ex- 

 tremely useful in irrigating rice lands. 



You have submitted to me also a number of 

 questions, and I have much pleasure in putting 

 the same again under your notice, together with 

 my replies thereto, given seriatim, and which will, 

 1 think, be found perfectly clear and satisfactory. 



I am very happy to learn that many rice plan- 

 tations in your quarter of the world require lo be 

 improved and benefited in the way you fioint ou'. 

 that much uncultivated laijd also may be. brouffhi 

 into use, with a cheap and durable apparatus lor 

 irrigation and draining. 



In the low lands throughout England, the pa- 

 tent pumps are tjetting into general use, and all 

 the old methods are being last laid aside. \Vc 

 are beginning now lo experience a good conti- 

 nental demand, atid have lately had with us a de- 

 putation irom the king of Holland, to consult on 

 the draining of ihe Haerlem lake. 



1 am quite sure, if 1 can have the honor of a li- 

 beral correspoiidence wiih you, no doubt can ex- 

 ist but a considerable number of our machines, 

 both as pumps and as hydraulicans, will be readi- 

 ly and advantageously disposed of. 



And if) on the receipt of these my refepecle, you 



will indicate from ilie descriptions given, what 

 machines sliall be l^jrwarded to you, at the same 

 lime fiivoring me with your remiilaiices lo any 

 amount you may think proper, Irom £50 lo £500, 

 you may de|)end that the machinery shall be pre- 

 pared and forwarded witli the utmost care and at- 

 tention, and that the prices charued lor Ihe same 

 phall be the very lowest possible, to inpiire Ihe car- 

 tying out a liberal correspondence. Waiting the 

 favor of your tidvices, I am, with respect, sir, 

 your most obedient servant, 



John Beare. 



Ques. 1st. What quantity of water can be 

 raised per minute li'om five to nine feet high, by 

 a tcn-horse-power steam engine driving a pump 

 or pumps'? 



Ans. 1st., We are now workinsr a pair of hy- 

 draulicans under my patents, with a ten-horse- 

 power steam engine, and this pair of pumps deli- 

 ver, at an altitude of eleven feet, twenty Ions of 

 water jier minute, two hundred and ten imperial 

 irallons to the ton, and a cubic foot of water being 

 sixty-two and a quarter pounds, the stream pro- 

 duced by this pair of pumps, when in flill action, 

 is nine leel wiile and fourteen inches deep. 



Q. 2d. Will it make a difl^erence in the working 

 of the pumps, if it be placed in tide water, which 

 rises and falls six leet. 



-•/. The'eff'ect of tide water is quite immaterial, 

 otherwise ihan when the water is highest, the 

 pumps vvill. work ihe lightest. 



Q. 3d. How many pumps, and what power 

 will be necessary lo raise seven hundred and 

 ihirly.-five cubic i'eex of water per minute, from 

 five 10 nine lt,'et high 1 



ji. Reckoning the cubic foot of water at sixty- 

 two and a quarter pounds avoirdupois, and ten 

 pounds being the imperial gallon, seven hundred 

 and thirty-five cubic feet of water per minute will 

 be, equal to twenty-one tons, eighty-three gallons 

 per reiinute. An^, as lifting from five to nine feet 

 high only, is so much less than eleven leet, as 

 slated in answer to query No. 1., a ten-horse en- 

 gine to this power lift, would give by the pair of 

 pumps about nine hundred cubic feet, or twenty- 

 six tons, one hundred and sixty-five gallons of 

 waier per minute. 



Q. 4. Will your patent pumps be less liable to 

 injury from aliernaie cold and heat, moisture and 

 dryness, Ihan llie pumps in ordinary use? 

 . jI. The pateni hydraulicans can take no injury, 

 if. I he workins paris are kept well oiled. 



Q. 5ih. Can your pump, if it becomes damaged, 

 or worn by Use,- he repaired [<}• mecluuiics, not 

 particularly drilled to such work? 



j-J. The palen! pumps can readily be refitted by 

 any oife capable of handling a tool, requiring no 

 nicety. 



Q. 6th. What vvill be the price of a pump or 

 pumps which will raise i=cven hundred and thirty- 

 five cubic feel of waier from five to nine feet high 

 per minute ? 



j^. The price of a pair of pntppt hydraulicans, 

 a.'j set foTlh in an.^wer to qupry No. 1, and to carry 

 out the work iherein elated, will be £265. 



Q. 7ih. Will either manual labor, horse power, 

 or a wind mill be as cheap and effectual in work- 

 ing your pumps, as a steam engine? 



.i^. Cannot estimate the cost of manual labor 

 with you. Wind is proved a bad motive-power
