The table shows a material that compares favorably with most of 
the coals sold on the Pacific coast. It is, indeed, their superior as 
regards calorific power, ash, and amount of sulphur. The amount 
indicated in the table as soluble in gasoline represents the petroleum 
residue present, the remaining 31.80 per cent consisting of peat and 
earthy material. 
PROPERTIES OF THE ALASKA PETROLEUM. 
Controller Bay petroleum. — A sample of the petroleum from the 
well near Katalla has been tested by Penniman & Browne, of Bal- 
timore, with the following results: 
Test of petroleum from Katalla, 
Specific gravity (0.828 at 15.5° C.) 39.1° B 
Distillation by Engler's method : 
Benzine (80°-J50° C.) 21%, 54.9° B. (0.7573) 
Burning oil (150°-300° C.) 51%, 40.6° B. (0.8204) 
Residiuni (paraffin base) 28%, 23.9° B. (0.9096) 
Sulphur Trace 
The burning oil was purified by concentrated sulphuric acid and soda, the vol- 
ume of acid used up being too small to measure. The purified burning oil was 
put into a small lamp, where it burned dry without incrusting the wick or cor- 
roding the burner, and without any marked diminution of flame. The burning 
pil compares very favorably in these respects with Pennsylvania oil prepared in 
the same way. 
The following analysis of this petroleum was published by Mr. 
Oliphant : a 
Analyis of petroleum from Katalla Bay well. 
Specific gravity at 60° F., 0.7958, equal to 45.9° Baume. 
Cold test did not chill at 3° F. below zero. Percent. 
Distillation below 150° C, naphtha 38.5
