Total gallons. 

 Total for 1863. 



In addition to the above, there has been exported to foreign ports, since 

 1st January, from Boston, 939,891 gallons; from Philadelphia, 1,377,039 

 gallons; from Baltimore, 364,806 gallons; and from Portland, 155,463 

 gallons — total 2,837,199 gallons — making a total export from the United 

 States, since 1st January, of 9,831,717 gallons. 



Mr. Page. — I believe that the supply of petroleum is like the supply of 

 coal, almost inexhaustible. Canada is full of it, Oregon, Ohio, and Califor- 

 nia, West Indies, Ceylon. There are, no doubt, millions of gallons lying in 

 the earth, like the gold in California. When the oil was first discovered it 

 had to be pumped up, but nature then came to the assistance of man, and 

 forced it up. Last year petroleum was sold for nine cents a gallon ; it is 

 now sixteen. We have lately sent from 3,000 to 4,000 barrels a day to Ger- 

 many, and it is going to the very place where they have it under their 

 feet. Japan is full of it, and I have been told that they burn it in the 

 streets of Japan by placing the oil in wooden tubes, and then lighting it. 

 The uses to which it can be applied are very numerous, and I should like 

 to see it employed as fuel in steam boilers. 



Dr. Rich. — Several years ago I was present when a plan was brought 

 before the American Institute for a railroad in Broadway, to be under the 

 street. The idea was to build a vault under the roadway; the advantages 

 claimed for it were, that it would be out of the way of vehicles, and warm 

 in winter and cool in summer, easy of access at all times, and very dry; it 

 was to be lighted throughout with gas; the speed could also be increased 

 to twice that above ground, and fires would not interfere with their run- 

 ning. The plan appeared to be perfect in every detail.
