The opening of the Ilium coal mine was begun with energy, but without many omens of success.  Philip was running a tunnel into the breast of the mountain, in faith that the coal stratum ran there as it ought to.  How far he must go in he believed he knew, but no one could tell exactly.  Some of the miners said that they should probably go through the mountain, and that the hole could be used for a railway tunnel.  The mining camp was a busy place at any rate.  Quite a settlement of board and log shanties had gone up, with a blacksmith shop, a small machine shop, and a temporary store for supplying the wants of the workmen.  Philip and Harry pitched a commodious tent, and lived in the full enjoyment of the free life.

There is no difficulty in digging a bole in the ground, if you have money enough to pay for the digging, but those who try this sort of work are always surprised at the large amount of money necessary to make a small hole.  The earth is never willing to yield one product, hidden in her bosom, without an equivalent for it.  And when a person asks of her coal, she is quite apt to require gold in exchange.

It was exciting work for all concerned in it.  As the tunnel advanced into the rock every day promised to be the golden day.  This very blast might disclose the treasure.

The work went on week after week, and at length during the night as well as the daytime.  Gangs relieved each other, and the tunnel was every hour, inch by inch and foot by foot, crawling into the mountain.  Philip was on the stretch of hope and excitement.  Every pay day he saw his funds melting away, and still there was only the faintest show of what the miners call “signs.”

The life suited Harry, whose buoyant hopefulness was never disturbed.  He made endless calculations, which nobody could understand, of the probable position of the vein.  He stood about among the workmen with the busiest air.  When he was down at Ilium he called himself the engineer of the works, and he used to spend hours smoking his pipe with the Dutch landlord on the hotel porch, and astonishing the idlers there with the stories of his railroad operations in Missouri.  He talked with the landlord, too, about enlarging his hotel, and about buying some village lots, in the prospect of a rise, when the mine was opened.  He taught the Dutchman how to mix a great many cooling drinks for the summer time, and had a bill at the hotel, the growing length of which Mr. Dusenheimer contemplated with pleasant anticipations.  Mr. Brierly was a very useful and cheering person wherever he went.

Midsummer arrived:  Philip could report to Mr. Bolton only progress, and this was not a cheerful message for him to send to Philadelphia in reply to inquiries that he thought became more and more anxious.  Philip himself was a prey to the constant fear that the money would give out before the coal was struck.
