Clover.

White clover growing among the Red does not lessen the crop of the latter. Logan.

Try two Rotations, differing only in the circumstance that one has 3. years of red clover, & the other 3. years of rest, either successive or interspersed, & at the close of the rotation, that with the clover will be very much more ameliorated, than the field which had 3. years of rest. Logan.

Dr Logan sows his clover alone in the fall

the next summer is it’s prime, yielding 2 cuttings.

the following year gives one cutting & pasture instead of a 2d

his average cuttings are 2. tons to the acre.

wheat sowed on it after 2. years crops, yield the heaviest crop possible, as the ground is still clear of weeds.

if the want of spring pasture renders expedient to let it remain still another year, then, to get rid of weeds, it will require an extra ploughing.

The 2d cutting is generally best for the quantity, & always for the quality of the hay.

it is also best for the seed: Peters.

the 1st cutting is before harvest, & the 2d after.

Clover hay, if well stacked, will spoil but a little way in. however it is best to put it under barracks.

hay is generally stacked in Pensylva in stacks of about 3, 4, or 5 tons; but in England they pack in 15 or 20. tons, as hard as wood. it keeps the better the larger the stack, & the harder packed.

clover when dried weighs ¼ of what it did when green. Kaim. 168.

the Seed produced is very precarious in quantity. Dr Logan thinks 2. bushels an average crop: Peters 4. bushels, & he has seen vastly more to the acre. the heads are combed off, which does not sacrifice the hay.

Young’s experiments yeilded on an average 2¾ bush. to the acre. he made [. . .] it from the 2d crop. he suspects that, contrary to the common opinion, when clover seeds it injures the succeeding crop, whether clover or grain. 3. Young’s exp. agri. 300. 360.

the quantity of seed to an acre producing the maximum is in manured lands

12½ . pa. 393
unmanured 20.  pa. 387

[these quantities sown by hand are but equivalent to 4½ and 7½ sown with the box]

his experiments are decisive against autumnal sowing. ib. 367.

he thinks it best to continue clover 3. years on the land. ib. 321.

it is the best summer feed for hogs. ib. 292.

a field of 10. as will pasture more than 2. fields of 5. as each. ib. 299.
