FARMERS' REGISTER 



[No. 9 



friends. But there have been so many such demands 

 on our time and labor, that a part have been necessa- 

 rily neglected, and others have been attended to only 

 after much delay. 



It has occurred to us that the wishes and convenience 

 of all parties might be promoted by the establishment 

 of a suitable laboratory for this limited but useful 

 branch of operative chemistry, and making it the bu- 

 siness of a competent operator to examine all speci- 

 mens of marl, &,c. sent for that purpose. This, like 

 every other kind of mechanical labor, can be executed 

 more easily and cheaply, as well as more perfectly, on 

 a large than on a small scale. With suitable apparatus 

 and arrangements, an operator could test the strength 

 of twenty specimens of marl, with more ease and cor- 

 rectness than a single specimen, if tried alone, and un- 

 der the ordinary disadvantages. If therefore such a 

 new business was enough encouraged, correct trials of 

 specimens and reports might be obtained at a less cost 

 for each, than the mere trouble attending a single trial 

 even to the experienced and skilful analyst. 



Any persons who may desire to obtain such services, 

 for their mvn private convenience or profit, may send 

 specimens for examination, to our care — and should the 

 demand justify the means, a competent operator will 

 be induced to undertake the trouble, for the profit. Our 

 apparatus (Davy's, as well as Rogers',) and our instruc- 

 tions,will be given in aid of the objects, and such gen- 

 eral attention as will secure our entire confidence in the 

 correctness of the results reported. If no other con- 

 veyance offers, very small specimens (say 20 grains 

 each,) may be sent by mail, postage paid. In that case, 

 each specimen should be dried, pounded and secured by 

 paste in a separate small paper cover. The postage 

 on an ounce package is the same as on a quadruple 

 letter. If larger specimens are sent, so as to show the 

 appearance of the earth as presented naturally, they 

 should be well wrapped separately, to prevent any com- 

 munication or mixture, and the whole closely packed 

 in a strong box, for transportation. 



The charge for such examinations must depend 

 somewhat on the extent of the business: but it cannot 

 exceed 50 cents for a single specimen — nor half that 

 rate for each of 20 specimens provided at once. It 

 should be understood that the proportion of calcareous 

 earth (or carbonate of lime,) contained, is the only ingre- 

 dient which is undertaken to be ascertained with cer- 

 tainty. Other ingredients (if supposed to be present, 

 and required to be known,) might demand not only far 

 more labor, but also more skill and science then we 

 would promise could be exercised. 



CHANGE OF ADDRESS NOTICE TO CORRES- 

 PONDENTS AND SUBSCRIBERS TO THE FAR- 

 MERS' REGISTER. 



The Farmers' Register will hereafter be published 

 in Petersburg, Va. to which place all letters to the edi- 

 tor must be directed. As the editor has no longer the 

 franking privilege, (as postmaster,) and as the widely 

 extended correspondence which exists, (and is neces- 

 sary, for properly conducting such a publication,) will 

 make the tax of postage very heavy under any circum- 



stances, he requests of his patrons and correspondents, 

 so far as their convenience may permit, to adopt such 

 modes of transmitting payments, and other communi- 

 cations on private business, as may somewhat lessen 

 this burden. 



The change of circumstances especially requires 

 that the editor should withdraw his former request to 

 have small specimens of particular soils, &c. sent by 

 mail for examination. By the attention paid to that 

 request by several correspondents, he has been greatly 

 obliged, and he may dare to say, that agricultural sci- 

 ence has been thereby advanced. 



VOI.. I. of farmers' register. 



By procuring some of the deficient Nos. a few more 

 copies of Vol. I. have been made complete, and may 

 be obtained at $5, by the earliest applicants for entire 

 sets of the work, including the current Vol. III. 



For any single No. of the first Vol. from 1 to 9, in- 

 clusive, returned uninjured, and free of postage, a No. 

 of Vol. II. or III. will be given in exchange. For 

 each one of a few copies of Nos. 2 and 6, Vol. I. $1 

 will be paid on delivery, or 3 later odd Nos. The se- 

 cond Vol. bound up with the Essay on Calcareous Ma- 

 nures will be given for each set of the first 9 Nos. of 

 Vol. I. returned as above.
