702 Iiejwrt on the Trials of Imjilemcnts at Bedford. 



fIS'G square feet, being IG ft. 1 in. long x 6 ft. 1\ in. broarl. The front wheels 

 have a diameter of 3 ft. 5 in., with 43° inclination to vertical, and 10 spokes ; 

 the hind wheels, 4 ft. 10 in., with 5° inclination, and 12 spokes. Tyres convex 

 and 4 inches broad. The axles are double, 2-4 inches square, and 20 inches 

 long, and are bolted to the axle-bed and lower bolster by a strong clip, and at 

 the end by a bolt 1 inch square. The fore carriage turns upon a pin. A slipper 

 is used instead of a lever-break. 



The weight of the waggon is 21 cwt. 2 qvs. 24 lbs. The mean draught on 

 the road per ton of gross load was 51 • 2 lbs., and per ton of useful load 65 ' 2 lbs., 

 while in the field these were respectively 203 lbs. and 258 lbs. ; therefore the 

 draught is somewhat high. Its price is also somewhat high, 42^. ; but the con- 

 struction, materials, and adaptability for general farm purposes are good. 



No. 5038. F. P. Milford, of Kmn, Exeter. — The construction of this wag- 

 gon is similar to No. 6036 in Class XX., only heavier, with broader tyres on 

 the wheels. Its draught was low both on the road and in the field ; but it is 

 Dot so well finished as some of the other waggons, and its i^rice is 40Z. 



Prize of 101. to W. Ball and Son (1308), of Rothwell, Kettering. 

 Highly Commended. — T. Milford and Son (4876), of Cullompton ; George 

 Ball (1240), of North Kilworth, Ivugby, 



Commended.— F. V. Milford (5038), of Kenn, Exeter.

Section V. — Carts. 



As previously shown, the mean draught of carts, eitlier per 

 ton of gross load or per ton of useful load, was much less than in 

 waggons, and especially so in going through the oat-field ; and 

 this difference Avould certainly have been still greater had the 

 soil been damp and soft ; the reason of this is, that the 

 whole load rests upon wheels of large diameter, whereas in 

 the waggons one-third, and sometimes nearly one-half of the 

 total load, rests upon the fore-wheels which are necessarily of 

 smaller diameter than the hind-wheels. In a cart there is some 

 weight thrown on to the horse's back ; but this, as will be seen 

 in the Tables, Class XXIII., was in most cases nearly reduced to 

 one-half when the cart was drawn along the field ; showing that, 

 as the draught was increased, part of the weight on the back 

 was thrown upon the shoulders. There are only two exceptions 

 to this, namely, in T. Milford and Son's and Hayes and Son's 

 ■carts, where the load on the horse's back was increased in the 

 field, probably owing to the higher point-attachment of the shafts 

 to the cart, and therefore more horizontal line of draught. In 

 these carts the height of the floors was greatest in their class. 



It would have been interesting to see the effect of the load 

 on the horse's back in going over hilly ground, as this is fre- 

 quently considered a disadvantage in carts ; but the trial-course 

 was very level, being only one gradient in 430 on the road, 

 and one in 1000 in the field.
