maple are also used but some object to maple because it is said that 

 where the iron skein is clamped to maple the axle will not last as long- 

 as with the oaks, owing- to dry rot caused by contact with the metal. 

 In many parts of the country steel axles are replacing oak, this being 

 especially true in the Mississippi valley and eastern states. Statis- 

 tics show that this change has been very rapid, having reached an 

 average of about seventy-five percent during the past decade. The 

 average cost of the steel axle is about $10 per set more than wood. 

 Besides wagons, carriages and automobiles, there are included 

 under this industry such vehicles as warehouse trucks, push carts, 

 sleighs and cutters; but it is unnecessary to mention in detail the 

 woods that enter into their manufacture, because the requirements 

 are the same as for other vehicles. No doubt not a little of the hard 

 maple reported is utilized for bobsleds and cutter sleighs, owing to 

 its strength and rigidity, as well as its lower price.
