No. 144.] 21 



1. An engine driven by steam, applicable to all descriptions of 

 draught. This engine differs from the locomotives in common 

 use, in being capable of moving and drawing loads upon ground 

 of any description capable of tillage, and consequently upon com- 

 mon and plank roads ; in the property of being turned around 

 an axis, passing through its own centre of gravity, and there- 

 fore within its own length; in that of allowing its wheels to be 

 geered to considerable differences of velocity, and in all cases to 

 velocities far less than would be given without geering, to wheels 

 of the same great diameter. It therefore appears to the commit- 

 tee that Mr. Cowing has foreseen and applied remedies for those 

 diflBlculties which would be encountered in the use for agricultu- 

 ral purposes of locomotives constructed upon the usual principles. 



2. Gangs of plows to be drawn by the above described steam 

 engine. These are planned and arranged in various manners for 

 the purpose of meeting the variety of operations that are desirable 

 in agriculture. Thus : One of the gangs is arranged for subsoil- 

 ing ; another for cultivating or horse-hoeing plants arranged in 

 rows or hills, and these are so adjusted that they may be shifted 

 in their position so as to throw the earth either to or from the 

 plant, as circumstances may require ; a third set is so arranged that 

 a great depth may be reached, and the soil broken up in succes- 

 sive slices, thus allowing the earth to be thoroughly pulverized 

 before sowing or planting ; in a fourth arrangement it is pro- 

 posed to cover seed sown broadcast to an uniform depth, while 

 the soil is at the same time harrowed and rolled. 



3. A machine to be worked by the same locomotive, and in- 

 tended for ditching to any desirable depth. 



Your committee are of opinion that all these diflferent instru- 

 ments manifest great ingenuity on the part of their inventor, and 

 are well worthy of the notice of agriculturists who are possessed 

 of large tracts of land of tolerably uniform surface. It is there- 

 fore very desirable tha^ these different instruments, and particu- 

 larly the locomotive, should be subjected to the test of experi- 

 ment, by which alone their absolute and relative value can be 

 properly tested.
