250 DRAUGHT AND HARNESS. 



seems to be encouraged to exert its strength from 

 finding that an immediate result follows its first effort. 



A well-arranged series of experiments instituted with 

 the horse-saver, by the section of the Agricultural 

 Institute of Halle, devoted to the trial of machinery, 

 shows that Fehrmann's traction- springs or horse-savers,, 

 afford an increase of tractional power of the horse,, 

 amounting to from 18 to 20 per cent. ; a diminution 

 of the shock transmitted to the legs and breast of 22 

 to 33 per cent., and of wear and tear of vehicle and 

 harness of the same amount. These experiments were 

 made on pavement, on steep hills, over ploughed land,, 

 and both in trot and at a walk, so that they seem very 

 reliable. The author has not himself had any personal 

 experience on the subject, but the authority on which 

 the above statements are made being official and 

 perfectly independent, deserves credence. 



The horse-saver is manufactured in several forms- 

 adapted to various purposes, as for instance a single one 

 may be made to suffice for the swinging bars used for a. 

 pair of horses, or two may be employed for the same, 

 one being attached behind each of the smaller bars,, 

 or as has been already pointed out, one may be attached 

 to each trace. There is also a modification applicable to- 

 the fixed splinter-bar of private carriages. The strength 

 of these instruments varies, some being applicable for 

 loads under 30 cwt., and others for loads from 50 cwt.. 

 up to five tons.* 



It is well known that the use of springs diminishes- 



* The inventor and patentee, Mr. C. L. Fehrmann, manufactures 

 the various kinds of Horse-Saver at Berlin (No. 27, Oranienburger 

 Street) . They may also be had from A. Lace, Agricultural Implement, 

 Maker and Commission Agent, Chisbury, Gt. Bedwyn, Hungerford,,
