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 fertilizers the importance of dealing with this matter as a broad and funda- 
mental problem affecting the basic matter of food supply. 
Bulletin 102, part 3. Sulphur: An example of industrial inde- 
pendence, by Joseph E. Pogue. Issued Nov. 7, 1917. 10 pp., 1 fig., 
3 pis. 
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 development has shifted 
the world’s largest sulphur industry from Sicily to the United States. The 
geological occurrence and method 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 determination of the sulphur resources present in the whole Gulf 
region, with a view to defining a proper adjustment between the needs of the 
sulphur industry and the sulphuric acid industry. 
Bulletin 102, part 4. Coal: The resource and its full utilization, 
by Chester G. Gilbert and Joseph E. Pogue. Issued Feb. 21, 1918, 
26 pp. 
The cost of fuel in the home is roughly four or five times the first cost at 
the mine. In other words, the cost to the consumer is out of all proportion to 
the price at the producing end. This discrepency means an extravagant price 
for fuel in the home and is due to wastefulness of economic procedure all the 
way down the line between production and consumption. It is the purpose of 
this paper to analyze the situation and point out economic changes needed to 
better conditions. 
Bulletin 102, part 5, Power: Its significance and needs, by 
Chester G. Gilbert and Joseph E. Pogue. Issued — , 1918. 
In this country tremendous emphasis is placed on the use of power ; the 
result is a growing burden on transportation which must be solved. The 
present transportation difficulty is in a measure an expression of this problem. 
The purpose of this paper is to develop the general nature of the situation and 
suggests the character of remedial action called for. 
Bulletin 102, part 6. Petroleum: A resource interpretation, by 
Chester G. Gilbert and Joseph E. Pogue. Issued Aug., 1918. 76 
pp., 12 figs., 3 pis. 
Petroleum is of particular significance because, of all our important resources, 
it is the most limited and involves the highest percentage of waste. Scarcely 
one-tenth of the value of the resource is recovered under present circumstances, 
while the unmined supply available under current practice is only about 70 
barrels per person. This paper makes an economic study of the resource and 
the industry engaged in its development and traces the causes of waste to 
certain maladjustments in the economic situation, pointing out how these may 
be remedied by a constructive economic policy applied to the matter. The 
desirability of developing shale oil to replace petroleum as it becomes in- 
capable of meeting the demand is gone into and the advisability of using 
benzol and alcohol as substitutes for gasoline is considered. The natural-gas 
industry is also treated.
