become a quasmirc ; let another difli be covered with the 

 fame (oil iit'ceea inches thick, and it is evident it will reciuire 

 fihcen times the number of cubic inches of water to put 

 this into the fame bogory (late. The former dlfo by twenty- 

 four hours dry \wather will become as hard as a brick, 

 when the other will onlv have a flight incrufiation formed 

 on the furface.. Suppofing tliis eHed to be produced on 

 your ticM, bv paffiuir the fixed harrow once acrols the land, 

 it will be put into altate of fine pulverization. By drilling 

 on three feet ridges, you keep the land in a dry healthy ftaie ; 

 and by fowing your fpring crop on the fame ridges, you ob- 

 viate the onlv objcftions to growing green winter crops oti 

 wet lands, viz. cutting up tlie land^ by carting off the crop, 

 and th^ impracticability of afterv ards preparing them tor 

 fpring fowing. In carting, thehorfcs w-alk in one furrow, 

 and the wheels track in two other furrows ; the tops ot the 

 ridges are always drv ; and the fixed harrow pafling twice in 

 a place, will prepare fuch lands for fowing, before the farmers 

 in the conmion mode of manygement, w ithout a crop ot green 

 food, can jutt a hnof on thei^r lands. Should furtace weeds 

 appear before fowing, Mr. Cooke's fcufllers, or broad (harts 

 tixed in the fcarifying-beam, ftiould be pafled through the 

 land.

\ E are fenfible that an editor of the biography of living 

 perfons (hould confiderhimfelf as in a very delicate fituation, 

 and the more refpertable the charafter who is his iub';e(it, the 

 greater (hould be his care; for utterly unmerited eulogy, from 

 motives of intereft or vanity, is fo ufual, that any praile at 

 all, or at leaft exceeding what is already generally conferred 

 and confeflcdly due, nuill be ofienfive to a man of inirinlic 

 iiierit. But thefe confiderations need not reftrain an editor 

 from gratifving the curiolily of the public, who may not 

 pcrfonally know a man of eminence, by a (tatemcnt at leall 

 of the departments in which he has been occupied, and a- 

 recital of his publiflied liicrary labours.
