The carriage with the short perch was loaded with 6 : 

 That with the long perch with . . , .,5:0 



When put in motion they kept together. 

 The load in the short perch carriage was placed at 



the top. They both kept together. 

 The springs of both were then prevented from acting. 

 S The short carriage had a load at top of . . . . 6:0 



The long carriage was loaded at bottom with . . 5:3 



The long carriage rather preceded. 



Comparison of Roads. 



Two roads were formed, one of gravel, the other of broken 

 stones ; two carriages without springs were connected with the 

 peirameter, one running on gravel, the other on stones; the 

 former having a load of 7 cvvt. the other of 4 cwt. ; they kept 

 nearly together. 



The same carriages were made to run, one on the broken 

 stones, the other on coarse pavement : 



The former had a load of . . . . . . 5 cwt. 



Tlie latter 17 cwt. 



The latter preceded. 

 In another experiment, 



The 1st had a load of .. .. .. 1 cwt. 



The 2d of lOcwt. 



They kept together. 



Experiments were also tried in order to ascertain the advan- 

 tage of covering the stones with straw, but little advantage 

 seemed to result. 



Your committee cannot close this Report without returning 

 their sincere thanks to Dr. Litton, for the zeal and intelligence 

 with which he attended and reported these experiments ; and 

 :ilso their perfect approbation of the unwearied attention and 

 skill vvith which Mr. William Edgeworth conducted the detail.
