ounce of soil, and its degree of inflammability, wifl 

 be the easiest test of the fertility of the specimen 

 tried . 



To aid a young beginner, I shall venture to re- 

 commend his reading the papers on this subject in 

 the 6th, 7th, 8th, and J2th volumes of the Annals 

 of Agriculture. 



Another method of examining soils deserving at- 

 tention is, by weighing them hydrostatically, as their 

 fertility will generally be in proportion to their spe- 

 cific levity, if the expression may be permitted. Fa. 

 broiu was, I believe, the first wlio recouu .tended this 

 test. He gives the following trials : 



Various soils, weighed hydrostatically, have given 

 the following result, the barometer being at 2,7-7, 

 and his thermometer at 13 : 



1 . The fertile soil of a wood, , ,.., 1,530 



2. A kindly soil, 1,582 



3. Green marl, * 1,591 



4. Penile earth of a friable staple, . . . 2, 100 



5. Volcanic earth, which does well for vines, 2, 1 1 1 



<5. Friable reddish earth, 2,131 



7. Strong land for wheat, vetches, &c 2, 1 60 



. Earth of a mountain, where iLo) cultivate olives, barley, 



&<: 2,200 



9. Sandy sterile land, 2, 120 



The ong evenings of December, will give a farmer 

 time for acquiring these branches of chemical know- 

 ledge.
