I have been thus diffase, Mr. Editor, on the Subject of clays and marls, that I may, if possible, justify in the opinions of their more distant bretbren, the practice of the farmers in this angle of Great Britain, apparently censurable for neg- Jecting 50 ebvious a mode of improving their farms as lime offers. The comparison will Stand thus in point of expenCce.

The expences therefore at first, independent of its necessary frequent repetition, are 50 evidently against,the lime, that nothing but its being a Suübsütute for manure,(which clay assuredly is not) could induce a man to make use of.it where clay or marl can be procured, unless with a view of varying ihe treatment of his land; a eircumstance, perhaps, not 50 much attended to as it deServes«.

Iam apttotbink, Mr. Editor, that your friend Farmer Sandy, “3 not much more conversant in chemical experintents than myself, or would he have asked,“ Suppose chalk might easily be powdered without caleination, what advantage. does A. N. expect from that operation!" I Speak with difidence; let one of your chemical friends pronounce, whether chalk, provided it be pulverized, has the zame effect on the Same s50il, in its burnt or unburnt State? It it 18 80, why incur the Unnecessary expence of burning it into lime? The frost will always act as a pulverizer, without any expence to the farmer. Surely there is Some inconsistency here in Farmer Sandy's an- 5wer to my queries, of which he was not aware, as well as errer in his philosophy«.[ am, however, much obliged by his ready compliance with my wish, and remain his, as well as your
