Peas.

June is the proper time for planting peas, by which time, where they are to be mixed with corn, the corn may have been ploughed 3. Times. per Parker.

in Germany, Peas are sowed the same day with the oats.
as soon as they are all turned yellow, [they] are mowed with a scythe & left 4. or 5. days in the sun to get quite dry. then in the morning, when the dew on them will prevent their shattering, they are carted home and put into the barn loft, & about midwinter threshed, when they yield easily & without loss. they make 40. bushels to the acre. Weaver.

96. May. 10. in sowing with the drill plow a quart sowed 350. yards of furrow which at 4. feet rows would be 10½ quarts to the acre, or say 1¼ peck. this was of the white boiling pea of Europe, to wit their field pea, or split pea. sowing the same by hand, a quart sowed only 310. yards which is 11.85 quarts per acre, say 3. gallons. the proportions are exactly as 31 : 35 : or 32 : 36. or 8 : 9. so that the drill saves ⅛ of seed. in labor it saves the whole hand sowing, and the covering with a plow.
we find a great advantage in preceding the drill by a harrow. 2. horses will harrow 15. as a day
