'ammler.,1 COKING TESTS. 129 
ood, hard, heavy coke, slightly off color, and 429 pounds of ash and 
reeze. 
West Virginia No. 11. — Run-of-mine coal from mines Nos. 1 and 2 
i W. II. Coffman, Zenith, W. Va. 
This was the only coal from West Virginia which did not coke in 
le ovens. The charge consisted of 11,000 pounds. It was burned 
>r 67 hours, and when drawn consisted of ash mixed with raw, 
nburned coal. 
West Virginia No. 12. — Run-of-mine coal from Big Sandy Coal and 
!oke Company, Big Sandy, W. Va. 
Two tests of this coal were made, the first being unwashed and the 
3cond washed. The unwashed charge was 11,000 pounds. It was 
urned for 08 hours, and produced 7,082 pounds of coke, or 61.4 per 
ant, and 549 pounds of ash and breeze. The coke was of fair quality 
iid had a metallic ring. It was of good color, but showed cross frac- 
ares. The washed charge (p. 73) of the same coal weighed 8,000 
bunds, and was burned for 44 hours, producing 5,050 pounds, or 63.1 
er cent, of coke and 583 pounds of ash and breeze. The coke was of 
rge size and grayish color, but not particularly strong. 
CUPOLA TESTS OF COKE. 
In connection with the coking tests of the coals the cokes made in 
e beehive ovens were not only analyzed and tested by various labo- 
tory methods, but those which gave promise of value in foundry 
oducts were also tested in the cupolas of the model foundry connected 
ith the Louisiana Purchase Exposition. 
The testing of these cokes for foundry purposes was done under the 
I'pervision of a committee appointed for this purpose by the American 
>undry men's Association, the committee consisting of Dr. Richard 
oldenke, secretary of the association; Mr. Herbert E. Field, of 
clntosh, Hemphill & Co., Pittsburg, Pa., and Mr. W. J. Fogarty, 
the Magnetite Foundry Company, St. Louis, Mo. Two thousand 
•unds of each such coke — one dozen samples in all — were reserved 
r these tests, and the cupola tests were made under the immediate 
pervision of Doctor Moldenke, during the month of November, using 
this purpose two 36-inch small foundry cupolas, one of which was 
rnished by the Whiting Foundry Equipment Company, of Chicago, 
d the other by the J. S. McCormick Compan}^, of Pittsburg. 
The analyses of the cokes and the iron used in the tests have not yet 
en completed, however, and it is, therefore, thought best to delay 
publication of the results of these tests until the issuance of a later 
3ort, in which will be included the tests of other cokes to be made 
ring the next few months.
