be established. In fact it soon became evident in making the pre- 

 liminary studies, that it would be necessary to design the various 

 treating plants to fit the best of the available tracts. 



As a result of these studies, seven plants were established and 

 placed in operation in five states as outlined below: 



It will be noted from the above table that several of the plants 

 are not yet working to their capacities as now planned. In designing 

 the plants, the plans were made to provide for the total annual capac- 

 ities shown above. However, when they were built the initial capaci- 

 ties were made somewhat lower as indicated by the table, by omitting 

 in some cases tanks and in other cases pole handling equipment 

 which could readily be added in conformity with the plans, later 

 when the additional capacities would be required.

It might not .seem necessary to occupy a very great area in the 

 operation of a pole treating plant. However, experience with some 

 of the earlier plants indicated that a reasonably large yard was \er\- 

 desirable because of the number of poles necessarily carried in piles 

 on skids in the yard both in the untreated stock and in the treatetl 

 stock. In so far as practicable the poles in the various treating 

 plants are arranged in such a manner that each length and class is 

 piled -separateK'. This greatly facilitates handling the poles, but 

 re(iuires considerable sjjace. Ordinarily about <S0 pole ()ilcs are 

 necessary in a yard. 



From four to ten acres of land has been used for each of the various 

 pole treating yards. Fig. 2, which includes about half of a com- 

 paratively small capacitN' \ar<!, sliows the necessity for plcnt\- of 

 room for the pole piles.
