 the purpose of this paper to 

 analyze the situation and point 

 out economic changes needed to 

 better conditions.

 The fertilizer resources of the 

 United States are viewed in the 

 light of their importance under 

 war-time conditions, when, on 

 the one hand, an increasing sup- 

 ply is needed for the production 

 of an added output of foodstuffs, 

 and, on the other, the foreign 

 sources of supply from which 

 much of our mineral fertilizer 

 is drawn have been cut off or 

 endangered. The rather re- 

 markable circumstances that 

 this country has been dependent 

 upon Chile for nitrogen, upon 

 Germany for potash, and upon 

 Spain for pyrite used in the 

 manufacture of sulphuric acid, 

 is pointed out in respect to de- 

 veloping national independence 

 as regards the fundamental ma- 

 terials. The paper is accom- 

 panied by a chart which shows 

 in one expanse the whole fer- 

 tilizer situation, with particular 

 regard to the effects of the war

upon it. The purpose of the 

 paper is to emphasize to the 

 general public as well as to those 

 more directly interested in fer- 

 tilizers the importance of deal- 

 ing with this matter as a broad 

 and fundamental problem af- 

 fecting the basic matter of food 

 supply. 



Sulphur : an example of indus-

 Two sulphur deposits near 

 the Gulf coast in Louisiana and 

 Texas, worked by an ingenious 

 and efficient mechanical process, 

 not only are supplying practi- 

 cally all of the crude sulphur in 

 this country, but their develop- 

 ment has shifted the world's 

 largest sulphur industry from 

 Sicily to the United States. The 

 geological occurrence and meth- 

 od of working the Gulf deposits 

 by means of the Frasch process 

 are described in nontechnical 

 language. The bearing of these 

 deposits on the sulphuric-acid 

 situation is discussed and the 

 need pointed out for a determi- 

 nation of the sulphur resources 

 present in the whole Gulf re- 

 gion, with a view to defining a 

 proper adjustment between the 

 needs of the sulphur industry 

 and the sulphuric acid industry.
