214 lbs., and per ton of useful load 324 lbs. : thus showing a higher mean draught 

 on the road and field, of 28*57 per cent, and 1 '4 per cent, respectively, than in 

 Ball and Son's waggon, which must be owing to the less flexible springs upon 

 which the load rests, for in respect to diameter of wheels and inclination of 

 wheels, it possesses decided advantages over the latter. This is a well-con- 

 structed waggon, with good workmanship ; but the price, 53Z., is somewhat 

 high. 



No. 1307. W. Ball and Son, of Bothivell, Kettering. — The construction and 

 framing of the body are similar to those in waggon No. 1300, already described 

 in Class XX. The dimensions of the body are 10 ft. li in. x 4 ft. 0^ in. x 1 ft. 

 6 in., its capacity is 64 cubic feet, and area over ladders for harvest purposes 87

square feet. It rests upon two front and two hind longitudinal springs. The front 

 springs are composed of nine plates 2iin. x i in., and the hind springs of 

 eleven plates of similar dimensions and 3 ft. 8 in. long. The ends of the 

 springs are curled downwards and inwards ; thus the weight is not distributed 

 equally over all the plates. In the springs of the last-described waggon, 

 where their ends are curled upwards and inwards, the weight is thrown 

 into the centre of the springs, and must therefore press more equally 

 on all the plates. The opening of the front springs without a load was 3f 

 inches, and that of the hind springs 5f inches, while under a load of 35 cwt. 

 their openings were reduced to 2f inches and 2-^-^ inches, thus showing
