I so Jnstniments alluded to in this EssatJ. 



All these instruments may be considered as appendages 

 to the drill, all may be applied to' the same axis and wheels j 

 and as all of thcni are worked and directed by handles, by 

 more or les.^ pressure the depth may be regulated at plea- 

 sure. As I have been applied to by many gentlemen from 

 various parts of the kingdom for information as to the num- 

 ber of these instruments, and horscn requisite to cultivate 

 any given quanthty of Ir^nd, I shall take this method of 

 stating to the Board mv ideas on this subject. For keeping 

 one hundred acres of arable land in high tiltii and regularly 

 cropped, five horses would be necessary, two Suffolk ploughs, 

 one cultivator complete, one beam and handles, with only 

 the tillage scarifiers, one fixed harrow, and of>c drill w ifh 

 corn scariliers, and a set of flat hoes. I should also rcco'n- 

 niend two pair of wheels with axis, independent of the drill 

 wheels, which I could never use but for the purpose of drill- 

 ing, except on very particular occasions. It is unnecessary 

 to say, that one strong waggon and one light harvest ditto, 

 with three dung carts, would be necessary; one connnon 

 pair of harrows, and two roHcrs^ (one very heav^•, and onlv 

 five feet long, to follow the scarifiers,) and one common 

 roller for passing over the corn in the spring of the year. 

 Though an instrument not alluded to in this essay, I should 

 strongly recommend Mr. Cooke's chaff-cutter, with which 

 I cut almost all the straw raised upon my farm, which is 

 applied to the purposes of animal food, and bv passing 

 through the stomachs of the beasts is converted into strong 

 manure; one load worth three such as is usuallv made in 

 yards, which is little better than wet straw. I derive great 

 advantage also from a boiler invented bv Mr. Cooke, w hich 

 saves two-thirds of the fuel. Bv a tub over this boiler 1 

 steam seven four-bushel ba^s of ix)talf)es or turnips with 

 three pecks of coals. A tbrashrnw; machine, capable of being 

 removed easily from one barn to another, appears to n>e a 

 desideratum. The quantity of com which nnght be saved 

 by a complete niachiae of this sort would be of real national 

 importance. Thousrh the cultivator and fixed harrow may 

 be considered as appendages to the drill, yet thtv are ap- 

 plicable to the broad-cast husbandry, and would save, if gene- 

 rally used, more than half the connnon expense for tillage. 



Upon Drilling and Horse-hoeing. 



Drilling is an operation which requires but very little 

 attention. O.i this subject I shall only state the depth at 

 which the seed should be deposited, the quantity per acre, 

 and the width of the intervals, which appears to me, after 

 fourteen or fifteen years practice, to be the most eligible.
