THE NATURALISTS’ COMPANION. 
One method of extracting the silver 
from the sea is by simple affinity. Gran¬ 
ulated copper is suspended in the deep, 
and the silver salt contained there is de- 
solved and the silver is precipitated 
thereon, from which it is separated in 
the labratory. 
The sea is also known to contain cop¬ 
per in large quantities. From experi¬ 
ments made by the English chemist, 
Piesse, he declared that the blue color 
of parts of the Mediterranean Sea is due 
to ammonical salts of copper, while the 
greeness of others is due to the chloride 
of copper. Not only are copper and 
silver found in the sea, but also gold. 
By a number of experiments made 
with the ocean’s water, in different parts 
of the world, by chemists (myself among 
the number) we find by careful com- 
pution that the oceans of the globe can¬ 
not contain less than a hundred thous¬ 
and tons of gold in solution. 
It is, therefore,not difficult to chemi¬ 
cally account for the precipitation and 
deposit of these gold nuggets in pockets 
or crevices by the whirling eddies of 
that boiling sea. 
CORRESPONDENCE. 
I have about 400 arrowpoints,all found 
on father’s farm of 160 acres. 1 also 
have two axes, four hatchets, one toma¬ 
hawk and a number of minor implements 
all stone. The smaller axe has “G. W. 
1732” cut into it deeply. It has been 
cut on a long time, as it is considerably 
disintegrated although found a couple 
of feet below the surface.

Last summer I found a nest of the 
Cedarbird composed entirely of chest¬ 
nut blossoms, and a Black-lulled Cuc¬ 
koo’s nest partly of the same material. 
I found a Chewink’s nest containing 
three eggs and one of the Cowbird, with¬ 
in twenty-five feet of a watering trough 
by the side of a road. One of my 
friends found a two-storied nest of the 
Pewee. I also collected a set of 6 
Meadow Lark’s eggs, 5 of Catbird, 5 of 
Brown Thrasher, 6 of Summer Yellow- 
bird, and 5 of Orchard Oriole. I have 
an egg of the Purple Grackle, the coIot 
of which is a dull ashy-white with a few 
markings at the larger end, and is cover¬ 
ed with pimples. A. B. Roberts,

The following is a list of bird arrivals 
in this locality,continued from last issue; 
April 20th.—American Goldfinch. 
April 30th.—While out hunting with 
a friend, we secured a pair ol Blue-wing 
Teal. These birds are quite a rarity 
here at this time of year. They were 
stuffed by ye editor. Spotted Sandpiper 
seen. 
May 5th.—Snipe, Red-and-white- 
shouldered Blackbirds. 
May 6th—Wood Thrush, Baltimore 
Oriole, Whip-poor-will, Woodcock. 
May 7th.—Wilson’s Thrush, Night- 
hawk. 
May 8th.—Bobolink. 
Mr. M. Cook, Biockport’s taxider¬ 
mist, reports the shooting of a Sandhill 
crane, on Sandy Creek, near this place, 
on May 20th. Mr. Cook has the bird 
and pronounces it to be an extra large 
and fine specimen. 
While “sugaring” in the fall of 1884 
we captured a large specimen of Erebus 
Odora, a moth quite rare in this locality.

More than half of our birds have al¬ 
ready arrived, and the northward move¬ 
ment will be ended by the last of May.
