Bulletin 102, part 3. Sulphur: An example of industrial inde- 
pendence, by Joseph E. Pogue. Issued November 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 prac- 
tically 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 February 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 discrepancy 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. (In press.) 
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 pres- 
ent 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 1918. 74 pp., 12 
figs,, 8 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 TO 
barrels to each 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 incapable 
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. 
Note, — The papers listed above as parts of Bulletin 102 are mem- 
bers of a series entitled “ The Mineral Industries of the United 
States.”
