Upon thefe courfes it is remarked, that their effects 
lead to different conclufions : in the firlt courfe, in which 
there are four green fallow-crops, to two of the white or 
grain kind, little advantage is fliown except in the leav¬ 
ing of the land in fine tilth, and perfectly clean. Pota¬ 
toes appear to exhault; and the experimenter fuggefts, that 
eftimating thirty tons of yard-compoft, the proportion 
employed at any imaginable rate, the courfe cannot be 
advifeable; the lofs on the potatoe-crop would not, he 
thinks, be lefs than five pounds, nor would the turnips 
pay fo as to leave a profit equal to the expences of newly- 
broken-up lands for the firlt fix years. 
He however ftates the fecond as a more profitable courfe, 
from the great charge of the potatoes not being incurred ; 
and it Ihows that, though cabbages cannot be grown to 
any great advantage on fuch foils without manure, they 
may be of much utility by the pulverization and clean- 
nefs which they afford. Thegoodnefs of the grain-crops, 
evinces that they exhauft but little, and that it is of great 
importance to have few white crops in rotations. And 
the third, he confiders as explaining the neceff.ty of ma¬ 
nuring for potatoes on all foils except fuch as are rich 
and dry. With only two white crops in fix years, the 
land feems rather, it is obferved, to improve, notwit-h- 
ftanding the potatoe-crop. The goodnefs of the lalt crop 
of wheat, in companion with the firlt, proves, he fays, 
the fupeviority of cabbage and bean-crops, over thofe of 
beans and potatoes, in cleaning and rendering the ground 
fine and fit for the growth of wheat-crops, .in a perfeft 
manner. Course IV.

The experimenter obferves, that the refult of thefe courfes 
(hows, in the firlt, the utility of repeated bean-crops in 
cleaning land ; and, when combined with cabbages, in 
preferving the fertility- of fuch as is newly-broken-up. 
When compared with the firlt courfe, which ends in the 
fame way, its advantages alfo appear, he thinks, great in 
other rel'pe&s. By the two lad, the difadvantages attend¬ 
ing fucceffive crops of corn are particularly brought for¬ 
ward. And it is well remarked, that they alfo fnow that 
any fort of corn-crops will fucceed, to a certain extent, 
on lands recently broken up from the ftafe of old grafs or 
fward ; and that, for the firlt two or three years, they may 
afford a produce proportionate to the fort of crop that is 
fown or cultivated on them. But that the three laft years, 
on being compared with the three firft, the whole Itill in 
corn, the produft was in the ratio of gl. 14s. 5b. to 14I. 
18s. 7d. or a decreafe of more than 5I. while, in the 
preceding courfes, with better rotations, the products have 
fomewhat increafed. The difference is therefore enor¬ 
mous. The decline in the barley, and even the wheat- 
crops, notwithltanding the intervention of beans in the 
latter cafe, is very great. Befides, they leave the land in 
a bad condition, being in the fourth and lixth years fuch 
a bed of weeds as could not be half deltroyed by the hoe¬ 
ing of the beans i in thele inltances the land not being; 
left worth eleven lfifilings an acre, w'hile in lome of the 
preceding it w r as left of the value of fixteen. Thefe, he 
well remarks, are the prejudicial effects of adopting bad 
courfes of cropping, from the eircumltances of old grals- 
lands being capable of affording a good produce for a 
time. The fame conlequences may likewife, he thinks, 
take place, even upon foils of a much better quality, by 
fuch methods of cropping. It is evident, that they fhould 
therefore be avoided as much as poflibie, on all defcrip- 
tions of foil, by the correct farmer. The laft of thefe 
courfes not only exhibits the badnefs of the practice of 
taking fucceffive grain-crops, but that beans, by the aid 
of the hoeing-culture, cannot afford a produce, even on 
newly-broken-up land, that will fufficiently repay the. 
great trouble and expence of the farmer.
