mine and lias <strong>the</strong> same cliai-acleiistics as i-('j;ai'ds poor ro<strong>of</strong> aud tliickiiess<br />

<strong>of</strong> stone in <strong>the</strong> middle <strong>of</strong> <strong>the</strong> seam. The same method <strong>of</strong> working<br />

is also followed. The ventilation was fair during <strong>the</strong> year,<br />

Eldorado.—This mine was idle a portion <strong>of</strong> <strong>the</strong> year, as <strong>the</strong> lessees<br />

gave it up to <strong>the</strong> owner, who is now Avorking it. The condition <strong>of</strong> <strong>the</strong><br />

mine w^as very fair at <strong>the</strong> dillerent visits during <strong>the</strong> year. They have<br />

siruck a piece <strong>of</strong> poor coal in <strong>the</strong> main heading, and are now endeavoring<br />

to get beyond it, for <strong>the</strong>re is a great part <strong>of</strong> <strong>the</strong> property yet<br />

unworked.<br />

Edmiston.—This is a new mine, which was opened during <strong>the</strong> year<br />

for <strong>the</strong> purpose <strong>of</strong> supplying coal to <strong>the</strong> fire brick works, but <strong>the</strong>y have<br />

rot employed enough miners to come under <strong>the</strong> provisions <strong>of</strong><br />

law, but expect, in <strong>the</strong> coming year, to increase <strong>the</strong> force <strong>of</strong> miners.<br />

Mountaindale.—The bulk <strong>of</strong> <strong>the</strong> coal from this mine is used for<br />

coking purposes, and tlie vein, which is a little over two feet in thickness<br />

is a very good coking coal. The method <strong>of</strong> working is heading<br />

and air course; <strong>the</strong> rooms are driven up seventy yards and <strong>the</strong> pillar<br />

is <strong>the</strong>n brought back. The ventilation was fair during <strong>the</strong> year.<br />

This mine will soon be worked out, and a new one opened early <strong>the</strong><br />

coming jear.<br />

Pennsylvania.—This is a new mine opened <strong>the</strong> last year, located<br />

about one iiiiK' from Coalport, aud <strong>the</strong> vein will not average more than<br />

two and a half feet in thickness. The ro<strong>of</strong> is not very good, it being<br />

so full <strong>of</strong> water seams that it is dangerous to work, and <strong>the</strong> miners<br />

have to exercise great care in keeping <strong>the</strong>mselves safe. The plan is<br />

heading and air course, and rooms are driven up for a distance <strong>of</strong><br />

seviMity yards, aud <strong>the</strong>n <strong>the</strong> jiillar is pulled back. The ventilation<br />

and drainage were good.<br />

Oakland.—This is not a large mine, only about twenty miners being<br />

employed, and as <strong>the</strong> coal dips all (lie way in(o <strong>the</strong> hill (hey liave<br />

trouble with water, and have a small steam pump outside to pump it<br />

out. The condition <strong>of</strong> <strong>the</strong> mine was very fair at my dilTorent visits.<br />

They have put in a new furnace
