the necessary hold on the ground, they are 

 made sharp and thin. They therefore require 

 being frequently renewed ; and hence it generally 

 happens, that a horse which is much worked in 

 frosty weather, has his feet more broken and in- 

 jured, than in the common wear of many months. 



To prevent the necessity of frequent removes, 

 several expedients have been put in practice. 

 Sometimes a few nails, of a larger size than the 

 rest, have been so put in, that the heads stood 

 considerably beyond the level of the shoe ; but 

 when these did not break off, as was often the 

 case, thev soon wore down. 



At other times, nails with large heads, taper- 

 ing to a point, were screwed into the web of the 

 shoe. Of these, one was usually placed at the 

 toe, and one at each heel. And by this con- 

 trivance of the screw, it was iaiao-ined, that the 

 nails might be easily replaced when worn out. 

 They are apt, however, to break off at the neck, 

 and are too expensive for common use. 



There is, notwithstanding, another plan, 

 which, as far as it has been tried, justifies the 

 Author in recommending it.
