top of the boiler, at some point between its rear end and tlie beater, E, a perpendicular 

 pipe, C, is inserted into it, wbicb pipe abould be long enough to carry its upper end 

 to a height somewhat above the tallest cotton-plants. The pipe, C, is provided with 

 a stop-cock, D, and connects at its upper extremity with a cross-^iipe, M, of the form 

 as shown at Fig. 2, and to approach very near the ground at both its ends. In that 

 j)ortion of th.e pipe, M, that is horizontal are two stop-cocks, one upon either side of 

 the point of connection with pipe, C, which serves the purpose of stopping the issue 

 of steam either entirely, or upon one side only of the machine. At a point near and 

 below the flexures or elbows of the pipe, M, at which it turns towards the ground, on 

 both sides of the machine, and from this point down to the two extremities of the 

 said pipe, at short intervals, are inserted small short pipes, a, which, diminishing in 

 size to their extremities, where they come very nearly to a point, serve as vent-s or 

 jets for the escaping steam when the machine is in operation. Placed alongside the 

 pipe, M, in front of it, and in contact with it everywhere, excepting only for a little 

 space uearits top part, where it bends forward, as shown at Fig. 1, is another pipe, 

 K, exacrly corresponding with pipe, M, in size and shape, and provided with the 

 same number of precisely similar jet-pipes, a, that are so placed as to be exactly over 

 the corresponding jets in pipe, M, that is to say, at their extremities, and in the 

 closest possible contact therewith. The object of this is to insure the dripping of 

 the oil over the orifices from which the steam escapes. Over the center of the upper 

 and horizontal section of pipe, K, and connecting therewith by a short pipe, d, is placed 

 the reservoir A for oil. Stop-cocks in the pipe, K, near to and upon each side of tfce 

 pipe, d, prevent a flow of oil down either end of said pipe, K, or permit it to flow into 

 both or only one end, as occasion may require, at the pleasure of the operator. A plat- 

 form in front of the boiler or furnace is provided on which a supply of fuel may be 

 carried, a light railing or lattice-guard on the sides of the platform protecting it. A 

 driver's seat, P, is placed on this platform, under which a vessel of oil may be carried, 

 as well as other things needed in the operation of the machine. This invention may 

 be of any dimensions, to be drawn by one or more horses. "
