means of a species of crutch, which is carried on the side of 

 the plough, and which, when allowed to drop on the ground, 

 acts as a toggle, and lifts the plough ovit of the ground. The 

 plough is lifted clear of the ground and is held in that position 

 as long as may be required. As it is often desired to use 

 more than one plough, it is necessary that the steering arrange-

 be of a regular width. In Messrs. McLaren's plough the front

 one plough is in use, each steers automatically the one 

 behind it, the tiller of each plough being attached to the one 

 preceding. There is a vertical adjustment, by which the plough 

 can be set to work at any desired depth.

 of accumulators in a small electric light installation. All 

 who have had to do with domestic electric lighting know 

 the great cost and trouble entailed by the upkeep of 

 these appliances. There is a set of accumulators, but 

 very small ones, such as are used on motor cars. As prac- 

 tically all the current is delivered direct from the dynamo 

 to the lamps, the efficiency of the plant is naturally high, 

 the heavy accumulator loss being avoided. The battery
