The climate of Michigan is materially
modified by the great lakes that surround
it., softening and moistening the prevailing
winds. In consequence, although in about
40 to 46 degrees north latitude, the belt lol
country bordering on the eastern shore OF
| Lake Michigan for some miles back from
| the water, is becoming celebrated for the
perfection of its fruits and the certainty iot
| the crop. The State owes to the same
cause the most extensive and valuable
| forests of timber now to be found east .oi

1t has been demonstrated in London
| that men can be carried far more cheaply
than they can carry themselves. The labor
| ing man is conveyed to and from his home,
distances varying from one to six miles, for
one shilling week or less than two cents a
| trip. 1t is easy for him to see that his time
and strength saved are worth more than
| this to him in wages at his work, and that
| many times this can also be saved to him
in rent by fixing his residence out on the
railway. Accordingly two of the most
costly railways in England command by
this policy a laboring mems traffic which
IS nearly if not quite the most profitable
they enjoy.

| While waiting on some dog teams he

one which had been stranded on a small
| bay for two years. The sea was not deep
enough for it to float and it had "run into
| the ground" The square wall which faced
| his base of measurement was three hundred
and fifteen feet high, and a fraction over
| three-quarters of mile long Being al
most square-sided above the sea, the same
shape must have extended beneath it; and
| since by measurement made two days be-
! fore, the doctor had discovered that fresh

talized piece of Greenland had stranded in
a depth of nearly half a mile, A rude es-
