The experimenter remarks, that-the firft of thefe courfes 
fhows the exhaufting effects of potatoes in a ftill more 
evident manner ; but the effefts’.of the beans are fonte- 
what different than in the other cafes noticed above. It 
is fuppofed evident from the fecond, that barley fucceeds 
better after potatoes than wheat; while the inferiority of 
the. fecond crop proves that the preparation they afford is 
not perfeftly fuitable, and that the wheat that fucceeds 
is affefted by their deteriorating property. The third 
courfe not only confirms the different refults that have 
been hated, but affords, byra companion with the twelfth, 
proofs of the utility of having beans and wheat in alter- 
nate courfes.

It is remarked, that in the firft of thefe courfes, though 
the potatoes of the fourth crop were manured for as 
above, the poornefs of the wheat-crop, which was the only 
one of the grain kind in fix years, fhows the exhaufting 
effects of cabbage and turnip crops, when removed from 
the ground in combination with potatoes, to be confider- 
ablc ; and from the fecond it is evident, that cabbages, 
when not confirmed upon the land, are To prejudicial as 
not to permit the ameliorating powers of beans to fecure a 
favourable crop of wheat. Neither this nor the preceding 
courfe is therefore profitable. The lalt is ftated to be a courfe 
of nothing but Iofs, and which fhows, in addition, the ex¬ 
haufting effects of potatoes and cabbages to be great, when 
the cabbages are carried off the ground to be confumed in 
other fituations. Course XXVIII.

The experimenter obferves, that the courfes in which 
potatoes and cabbages, not confumed on the land, enter 
in any confiderable degree, all prove the fame thing, that,, 
under particular circumftances, they are both prejudicial 
in exhaufting the land; and that the two latter courfes, 
when compared with thofie of eleven and twelve, difplay 
the advantages of beans over potatoes and cabbages in a 
manner that is extremely obvious, and highly in their fa¬ 
vour.

Here it is fhown, that the profit of thefe courfes is too 
trifling to recommend them ; and the products of the fifth 
and iixth years’ crops are fuppofed to be lefs than they 
ought to be, from the circumltance of manure being ap¬ 
plied in the fourth, and there being only one grain-crop 
in the courfe; fo that potatoes, even when manured for, 
leave the foil in no very advantageous fttuation for the 
growth of wheat, though affifted by the cleaning and im¬ 
proving qualities of bean-crops. And that the fecond and 
third courfes are equally decifive in fhowing the exhauft¬ 
ing effects both of potatoe and cabbage crops, when not 
confumed on the land, as well as that they are courfe9 
that fliould feldom be employed, where they cannot be 
manured for, and be fed off by live flock.
