The WALLED LAKE IN IowA-Is 1T A Work OF
ARRIVE find the following communication in the
Davenport, Iowa, Gazette:
Editors Gazette Much has been said of this cele
orated Lake, and many erroneous opinions formed
IN relation to it. There many of these lakes in
Northern Iowa and Minnesota, and all located in
high open prairie, far away from any considerable
quantity of timber. | have visited some of them,
and although there exhibited many signs of art,
and some appearance of the handicratt of man, yet
could not for 4 moment be led to believe that it
was the work of human being. Most of these
lakes are upon high lands, and all such are
less walled up, have bluff shores from three to
ten feet high. This is the with those in Wright
county Boyar Lake is the same in Sac county
and has wall around part OF it, so wide that
drove my horses and buggy on the top of it. The
Twin In Calhoun county, present similar phenome-
ma. and are subjects of deep interest
These lakes some seven or eight miles long. by
three broad, and divided in the middle by an 18th
mus, not more than ten rods wide, which is of sand
washed up by the action of the waves. No rock an
pears upon the shore of these lakes so far as exam
ined, but Boyer Lake has rocks in and around it
My own conclusions were upon minute examination,
that these walls were made by the action of the hea-
w winds on these bleak praires at the time of the
annual breaking up of the ice, pressing the rock on
shore from year to year, until high embankments
are formed, and Oftentimes with much symmetry
and even beauty was at Boyer Lake some three
years since in the month of April while there was
broken ice of great thickness in the lake. and could
readily perceive, as thought, the work still going
on of walling up the lake.
Immense quantities of fish of various kinds were
floating on shore, having been crushed in the ice,
supplying food in abundance for many beasts and
birds of prey.
1t is beautiful country around these lakes which
are filled with the finest specimens of the nnv tribe
and places of resort for herds of the elk and deer
and IN the seasons of incubation myriads of the
feathered tribe resort there to rear their Young
The waters are not deep, but clear and cold being
fed probably by springs.
These lakes differ much from those upon the heads
OF Skunk or Des Moines rivers, which are broad
shallow and grassy, and the country in which they
lie Is almost dead level, and has the appearance OF
once having been vast sheet of water. Upon the
mead OF the Skunk, however settlements have been
made and the inhabitants in digging wells have uni
versay hadto go from twenty thirty feet for water
and at that depth have often cut through drit-w
deposits of oak and black walnut and one instance
log OF walnut was cut off in sound state, two feet
IN diameter, at the depth of twentv-four feet A
similar phenomena of ,oaled lakes NAV be found i'm
the Great Basin of the Rocky Mountains upon the
humboldt desert and in fact in that country of a
northern latitude, destitute of timber and where
the wind has such unbounded scope as it has uDop
many OF the praries of Iowa.
AN OLD LAND HUNTER.
New TOBACCO QUEsrIoN.-The important ques-
ton OF the possibility of poisoning by cigars i'm
pregnated with arsenic, has been raised states the
London Lancet, by the recent death in France of a
priest named Bottaro, supposed to have been poi
soned by another priest.
An investigation has been undertaken to as
certain whether it be possible or probable that
arsenlcated cigars death, by the in
SEPARATION of their smoke impregnated with vola-
hZed arsenic, or by its admission in the saliva
without such change; and very important are
the conclusions arrived at. There are three
ways" remark the investigators, sin which the
introduction of arsenic into the animal economy
may be effected through the medium of cigars:
by impregnation with a powerful solution of
