on two sides of a long pole rigidly attached to the plough has 

 the advantage of simplicity and cheapness. It does away 

 with the necessity of reins also, bullocks being guided by 

 a touch or twist of the tail with one hand while the single 

 stilt is held by the ploughman by the other. The improved 

 ploughs recognise the advantage of this simplicity and cheap- 

 ness. Figs. 18, 19, 20 and 21 illustrate the method of 

 attachment of one, two and three animals respectively to an 

 implement. Fig. 22 illustrates another method of attaching 

 three animals. 



175. Multiple ploughs. Two furrows are turned simul- 

 taneously with a Two-furrow-plough instead of one. The 

 draught is therefore much greater, and as three horses are 

 required to drive this plough, it is clearly unsuitable for 

 Indian bullocks. Having a wider bottom it does as even 

 and steady work on level soils free from stones, as the wheel- 

 plough. There are no side-plates or sole in this plough and 

 it does not therefore form pans. For preparing seed-bed on 

 ploughed land two horses can easily manage this plough. It 

 does twice as much work as the wheel or swing plough. 

 The three-furrow plough turns 3 furrow-slices at the same 

 time, each 9" wide, and it can plough 3 or 4 acres of land 

 per day if the soil is very light. Having a wide-bottom, the 

 draught is very heavy and 4 horses are required for drawing
