 during the past year, but so far as known no definite steps were 

 taken toward the establishment of an active industry. While it 

 is generally agreed among chemical technologists that there is no 

 special obstacle to the extraction of potash, so far as the methods 

 are concerned, opinion seems to be divided in regard to the com- 

 mercial outcome of the undertaking, in view of the probable reduc- 

 tion of market values with the close of the war. An establishment 

 on a commercial basis would have to be of large capacity and 

 would entail a correspondingly large initial outlay. The matter 

 thus becomes mainly of financial nature. 



Some difficulty would likely be encountered, however, in finding 

 a suitable location for such an establishment. Most of the large 

 feldspar deposits are situated in rather remote districts, where fuel 

 and other needed supplies are not readily to be had. Another
