1 have no doubt of Mr. Young's faithiul relation of these eccentric experiments, but admittivg their accuracy,[ Shall be glad to See that he or any otber geutleman, tbrough the medi- um of your Magazine, Ww 11 ex plain we WETIE ot this curious test of the colnparative v ralue of land.

By Some observations I have Seen inthe works of an ingent- ous chemist, L have been led to SupPpose that these erial ex- tracts pr'ceeded from the decompoziwon of water from the coaly matter ih the Soil, but I Link it will very much g ratity the wishes 61 your DIAG if Some of your 0 lligent COrres- pondents vc üld take the trouble to multiply facts zd experi- ments on this Subject, to.establish Some generai theory which might be extensively applied to the most important enquiries in agriculture,

To the Editor of the Agricultural Magazine. STR, Presume your work is designed particularly to detail all useful discoveries connected with the management of rural alfairs. While you reject what constitutes be amuzement of the drawing=room, and what agitates the tever of. the public opinion in populous cities, you arc disposed to divulge and to proclaim those inventions ot the ingenious artist, which can lessen the cares and diminish the labours ot the useful and re- Spectable body ot British peasantry.

One of the most valuable discoveries that was ever made for the. application. of inahimate force is the construction of the Water-Mill, Inthis country, this usetu] machine is applicd
