INSULATOR PINS AND BRACKETS. 

 Durability and strength are the requisite qualities of insulator pin- ma- 

 terial, and locust is the wood principally used in their manufacture. In the 

 country at large, its use for this purpose exceeds seven times the amount 

 of all other woods combined and in Pennsylvania over 425,000 feet are used 

 each year. White oak, red oak, elm, and osage orange are other woods 

 used for pins in various states, but, unlike locust, where these are em- 

 ployed they are ordinarily dipped in paint or some antiseptic solution, such 

 as creosote, in order to increase their durability. In Pennsylvania locust 

 was the only wood reported for insulator pins and the other woods appearing 

 in the table were used for pole brackets.

BUTCHERS' BLOCKS AND SKEWERS. 

 The two important woods for butchers blocks are sycamore and sugar 

 maple. On account of their desired qualities, hardness and uncleavability , 

 together with their strength and tastelessness, they are first among the do- 

 mestic woods for this use. Formerly butchers' blocks were round, usually
