    strate it to be of equal importance to the various classes of our countrymen, that the science should be cultivated with the same ardour in these king donis. The science we here recommend to your tegard, has for its objects every substance of the material world, and, therefore, is equally inter- ésting to every civilized nation upon earth. Is your son bora to opulence,—is he the heir to an extensive domain; make him an analytical chemist, and you enable him to appreciate the real value of his estate, aud to turn every acre of it to the best account. Has he a barren tract of country, which has been unproductive from ge- neration to generation ; he will explore its bowels with avidity for hidden treasures, and will proba~ bly mot explore it in vain. By analysing the minerals which he discovers; he will ascertain with facility and exactness what proportion of metal they contain, and which of them may be worked to profit. Thus-he will operate on sure grounds, and be prevented from engaging in ex-+ pensive and unprofitable undertakings. Chemistry will teach him also how to improve the cultivated parts of his estate; and by trans-— porting and transposing the different soils, how each may be rendered more productive. The ana- lysis of the soils will be followed by that of the waters which rise upon, or flow through, them ; by which means he will discover those proper for irrigation ; a practice the value of which is sufii- ciently known to every good agriculturist.
