528 THE LABCWATOfcY. [DEC* 



as this to form part of a Farmer's Calendar, would 

 have been thought an absurdity ; but such an opi- 

 nion will not, I trust, prevail at present. The in- 

 timate connexion between agriculture and chemistry 

 is unquestioned. Let it not, however, be imagined 

 that I propose a farmer should addict himself to a 

 pursuit which is not only very captivating but also 

 very expensive; I would merely have him able to an; 

 lyze* in a rough way, his soils, and the fossil ma- 

 nures which may be found under them ; for this pur- 

 pose the apparatus is not formidable : and for a la- 

 boratory, if he has a small blacksmith's shop and 

 forge (which no large farm should be without), it 

 will serve the purpose very well. It is only providing 

 a cupboard, under lock and key, to secure his glasses 

 and the other articles necessary for these experiments. 

 One caution, however, I must premise, if he has no 

 forge, and converts some other room to this purpose, 

 if it be attached to his house or offices, and a fire 

 (from whatever cause) should consume them, the 

 laboratory would vitiate his insurance at a fire-office, 

 unless he enters it, and pays for the whole as douHu 

 hazardous-, in the language of insuring. 



The apparatus nccc >nsists of the following 



particulars : A deal table with a drawer, which drawer 

 should be sufficiently short of the full breadth to allow 

 a range of holes in the upper surface for glass jars to 

 stand, free from clanger of lulling. 



Half a dozen glass cylindrical jars, nine or ton 

 inches long, and three or four inches diameter ; with 

 .i few of the same shape, but smaller. One or two 

 others, five or six iuciies diameter and eighteen inches 



long :
