furnished with a seat, like a sulky-plow, and the plowman may ride at 
ease. A plowman of very ordinary skill is competent to manage this 
implement. It may be set to turn two furrows, by attaching two rotary 
ld-boards to the machine. - Such are some of the points set forth in 
this novel invention, but it evidently requires a more complete trial and 
a more perfect adjustment, in order to meet the requirements of an ex- 
panding agricultural enterprise. The enormous extent of plow-man- 
ufacture is indicated in the statement of a new firm, making chilled- 
iron plows in the West. In 1871 they made 1,506 plows; in 1872, 
3,049 plows; in 1873, 7,472 plows; in 1874, 14,976 plows in 1875, 
31,077 plows. The orders received during 1875 exceeded the produc- 
tion by 10,000. The manufacture for 1876 has been fixed at 75,000 
plows asa minimum. Other statements, equally well attested, indicate 
a Similar increase in the production of plows by other firms. The culti- 
vator has become not less important to the farmer than the plow itself, 
and forms no less elaborate, embodying the latest application of econo- 
mic principles, are observable in this branch of production. A machine 
for pulverizing the soil, constructed like a harrow, with circular, sharp 
disks, instead of teeth, revolving upon shifting axes, is one of the nov- 
elties in this line of construction. Harrows are also exhibited in 
great variety and construction, both solid and jointed. In nearly all 
these cases the plow or cultivator is to be driven only by horse-power. 
No steam-plows are on exhibition by American exhibitors, as far as 
shown by the catalogue. 
The next class ef implements have relation to planting. Broadcast 
sowing still has its advocates and adherents among farmers, and to meet 
this requirement broadcast seeders are still invented, constructed, and 
sold. One hand-machine is offered at the Centennial which proposes to 
sow from 4 to 8 acres per hour. ‘The same machine mounted on wheels 
and drawn by two horses, it isclaimed, will seed from 10 to 15 acres per 
hour. It casts wheat from 30 to 36 feet; barley, from 27 to 33 feet; 
hemp, from 27 to 30 feet; and generally a heavy seed is thrown further 
than alight one. Another combines a cultivator with the sowing ap- 
paratus in order to break up corn-stalk ground without plowing. But 
broadcast devices are not numerous at the Exposition, while the drill is 
found in an immense variety of adaptations. Exhibitors, of course, are 
profoundly convinced of the superiority of their own machines, and itis 
not proposed in this article to pass any judgment upon their conflicting 
claims, but to indicate some leading characteristics of the wares on ex- 
hibition. The points of excellence claimed by different machines have 
respect, mainly, to the regulation of the depth at which the seed is 
deposited, and of the flow of seed through the pipes. The devices for fore- 
ing feed are put forward as prominent advantages by several exhibitors. 
Arrangements are made by which hoes are deflected by accidental obstruc- 
tions, such as stones, &c., without breaking. In some cases the quan- 
tity of seed discharged through the pipes is regulated automatically by 
an arrangement in the gearing which may be altered if desirable; in 
other cases the quantity is regulated by the driver. By a simple con- 
trivance, involving a very slight adjustment, the drill may be trans- 
formed into a wheel-hoe. A separate box for the distribution of some 
concentrated fertilizer with the seed is put forward as an especial excel- 
lence of some machines. Specific improvements are claimed in the 
method of gearing, in the arrangement of the draft, reducing resistance 
to a minimum, in the materials of which different parts of the mechan- 
ism are constructed, in securing a perfect equilibrium when in motion, 
in perfect ease in operating, in the elimination of straws and other ob-
