HOW TO CALCULATE THE WEIGHT OF LIVE STOCK. 
1. Find the girth in inches at the back of the shoulders, and the length in inches 
from the square of the buttock to a point even with the point of the shoulder blade. 
2. Multiply the girth by the length and divide the product by 144. hen 
multiply the result by the number of pounds per superficial foot for cattle of different 
girths ; the product of this will be the number of pounds of beef, veal, or pork in the 
four quarters of the animal. 
3. For cattle of a girth of from 5 to 7 feet, take 23 lb. to each superficial foot; 
and for a girth of from 7 to 9 feet, reckon 31 1b. to the superficial foot. 3 
4, For small cattle and calves of a girth of from 3 to 5 feet, 16 lb. to the foot; and 
for sheep, pigs, and all cattle measuring less than 3 feet, 11 1b. to the superficial foot, 
5. When the animal is but half fattened, a deduction of 14 lb. in every 280 lb, 
or 1 stone in every 20 stone, should be made; but, if very fat, 1 stone for every 20 
should be added. 
6. Suppose it is desired to ascertain the weight of an animal whose girth is 6 feet 
4 inches and length 5 feet 3 inches: 76 inches girth by 63 inches length = 4,788, 
4,788 + 144 = 33°25 superficial feet. Multiply this result by 23, and you will have 
76475 lb. or 544% stones. 
The deduction or addition mentioned in paragraph 5 should then be made, 
according as to whether the animal may be in ordinary or in very fat condition. 
THE IVEL AGRICULTURAL MOTOR. 
No doubt one of the features that will distinguish the twentieth from the 
nineteenth century will be the universal motor. Even a couple of years ago 
the motor was considered little more than a plaything for the rich, and though 
the automobile still remains for the greater part in this sphere there is no 
doubt that it has come to stay, and the process of perfection is only a matter 
of time. With a higher degree of perfection will come extended use in 
business, and it is not surprising to know that agriculture is receiving a share 
of the thought of inventors and improvers. ‘The automobile for marketing 
purposes is no new idea, and many may have dreamt of the horse as a matter 
of history in the cultivation of fields, but so far his position seems secure, 
That the next decade will find matters quite the same is by no means certain, 
and the latest invention to take his place in ordinary farm work is the Ivel 
agricultural motor. Anyone but an expert will get a better idea of the motor 
from the illustration opposite than columns of description would convey. It is 
driven by petrol, and is constructed to draw mowers, reapers, &c., which are 
joined to the motor by a spring coupling. It is designed for home work as 
well, and can be utilised for pulping, root-cutting, grinding, &c. In all this the 
inventor and maker, Mr. Dan Albone, Ivel Motor Works, Biggleswade, Beds, 
claims that it comes out in cost considerably less than horse Jabour. New 
inventions do not always fulfil the hopes of inventors, and whether this type of 
motor is designed to banish the horse from farm work remains to be seen. 
There seems little doubt, however, that so far as reaping and mowing is con- 
cerned it is a complete success. A demonstration was given on the farm of 
Mr. C. Capon, Hill Farm, about 2 miles from Biggleswade, on Wednesday, 23rd 
August, when, at a gathering of agriculturists, the latter were much impressed with 
the work of the machine attached to a mower. One of the local farmers offered 
to buy the machine if Mr. Albone would sell it. It was kept at work for about 
an hour and a-half, and everything passed off without a hitch. The speed was 
much greater than horses, being about 6 to 7 miles an hour, but the work was 
good, and, needless to say, quickly done. Mr. Aibone hopes to make the 
machine suitable for the plough or cultivator, but as it is it would often prove 
useful even on farms fully stocked with horses. One advantage of 
machinery is that it does not eat when not working, and evidently at a hurried 
time a machine like this could do much more in a day than a horsed mower.—
