construction — the wheel. 



The Hub of the wheel being at once its centre and foun- 

 dation, mechanically speaking, should be particularly strong 

 and of well-seasoned wood. Red elm, white elm, and 

 particularly the gum, are good timber for this part, as 

 they are not liable to crack in seasoning, or to split by the 

 pressure of the spokes. The modern form of the hub 

 is much shorter than that used even a dozen years ago, 

 and though it may have some advantages in crowded 

 thoroughfares, where, as on Broadway, New York, col- 

 lisions are frequent, it is undoubtedly a change for the 

 worse, so far as strength is concerned, as it gives a shorter 

 hold to the axle.
