In closing the history of this remarkable enterprise, one thought overshadows all others as we contemplate the author and his work.

It is the thought of the unsolved mysteries and sublimities and beauties of these mountains—their inaccessibility, their remoteness—had it not been for the persevering efforts of Prof. Lowe. The dark curtain that had hung for ages over these craggy chasms, these phenomenal canyons, these magnificent forests, these abysmal depths and cloud piercing heights, these grottoes and glens, these solitary habitations of bird and beast would still be drawn down but for his enterprise and genius—thus shutting out a thousand delights to the multitudes who have already looked upon them, and the myriads in the coming century who are yet to rejoice in their glories.
