can be moved from right to left, or from left to right, to regulate the 

 land of the plow or the width of the furrow. The points of the 

 beams can be raised or lowered in this attachment to regulate the 

 depth of the plowing. There is also what is called the hinge-axle, by 

 means of which the driver can vary the depth of the plows about five 

 inches without leaving his seat or stopping his horses. The plows are 

 raised out of the ground by a foot-lever, so that in turning at the cor- 

 ners, passing an obstruction, or driving from field to field, the driver 

 can throw his plows clear of the ground, and at the same time have 

 the use of both hands to manage his team. When desired, sub-soilers 

 can be attached to each plow, which will tear up the ground anv 

 depth required. The machine will plow the hardest ground fully 

 eighteen inches deep without the sub-soilers. All that is necessary 

 is power ; and the amount required will depend on the condition of 

 the ground, the depth of the plowing, and the width of the furrows. 

 The number of plows in the gang does not determine the amount of 

 power required so much as the size of the plows. Thus, four six-inch 

 plows will require no more power than two twelve-inch plows. If 

 any difference, they will require less ; and they will do a great deal 

 better work. I would greatly prefer small plows, and more of them, 

 to large plows, in a gang. I believe it would pay for all extra time, 

 even in the use of single plows, to have them smaller ; the narrower 

 the furrow the better the plowing. The objection is, the amount of 

 time it consumes. This objection is taken away when we work plows 

 in gangs. We can put on as many small plows as we have power to 

 draw'. With this machine, whether we use one plow or five ; whether 

 they are each six inches wide or fifteen ; whether we plow six inches 

 deep or two feet, the labor of only one man is required, and he has 

 little to do but drive his team. 



As to the economy of the use of the implement, I will present a 

 few points : 



First. For use as a common two-horse plow, it costs no more than 

 a wooden-stocked plow of equal quality and strength. Being made 

 entirely of iron and steel, no trouble, delay or expense is ever caused 

 by the breaking of a beam or handle. When the share and mould- 

 board are worn out, new ones can be put on the old stock for just 

 half the price of a new plow. As this can be repeated from time to 

 time, when these parts wear out, it is evident that, in a few years, it 

 will be a saving to the farmer worth noticing. 



By the use of the gang-plow, we save the labor of one man for 

 every plow attached after the first one ; and the saving of leg and arm-
