ory expedition to Nova Scotia, the first expedition of the kind in
this country. Two years later he built at his own expense, and in
part by the labor of his own hands, the astronomical observatory at
Williamstown. In this also, it is said, in advance of all others erected
exclusively for purposes of instruction. He was a devoted and profound
student, as well as an accomplished teacher, of natural science. But he
was still more distinguished for his piety and his religious influence
in the college. Hundreds of students in successive classes learned
to love and revere him as a holy man of God--many of them as their
spiritual father. The history of American colleges affords probably no
instance of a happier, or more remarkable, union of true science with
that personal holiness and zeal for God, by which hearts are won for
Christ. Full of faith and of the Holy Ghost, he did the work of an
evangelist for more than forty years--not in the college only, but all
over the town. During the last six years of his life he devoted himself
especially to the White Oaks--a district in the north-east part of
Williamstown-which had long before excited his sympathy on account of
the poverty, vice, and degradation which marked the neighborhood. He
identified himself with the population by buying and carrying on a small
farm among them. He also established a Sunday-school, and then he built
with the aid of friends a tasteful chapel, which was dedicated in
October, 1866. Later "the Church of Christ in the White Oaks" was
organised, and here, as his failing strength allowed, he preached and
labored the rest of his days.

Prof. Hopkins was an enthusiastic lover of nature. A few years before
his death he organised a society called "The Alpine Club," composed
chiefly of young ladies, with whom, as their chosen leader, he made
excursions summer after summer--camping out often among the hills. He
took them to many a picturesque nook and retreat, of which they had
never heard, in the mountains near by. He also explored with them other
interesting and remoter portions of northern Berkshire, and interpreted
to them on the spot the thoughts of God, as they appeared in the
infinitely varied and beautiful details of His works. In these
excursions he seemed as young as any of his young companions, with
feelings as fresh and joyous as theirs. In earlier years he was a very
grave man, with something of the old Puritan sternness in his looks and
ways, and h
