COLLECTING SHELLS 
IN DRIFT. 
BY V. STERKI, M. D. NEW PHILADELPHIA, O. 
3a this time of the year freshets are very 
prevalent throughout the country, and 
this very fact furnishes you with an ex- 
cellent opportunity to collect the smaller spe- 
cies of land and fresh-water shells. Gather 
carefully the fine drift deposited in smaller or 
larger quantities—sometimes very little and 
yet valuable—at the edge of high water, by 
basketfuls or even bushels, carry it home and 
let it dry upon a suitable piece of cloth, such 
an an old bed sheet. When the drift is dry, 
shake and rub it gently, pass it through a sieve 
or handle it otherwise so that the smaller par- 
ticles may be separated. Place these by hand- 
fuls upon the table and pick out the small 
shells with the aid of a fine pair of pincers. 
You will, in most instances, find many valuable 
specimens. 
Vertigos. 
Many of these shells will be more or less 
weathered, while a part of them will be found 
in good condition. | You may find species in 
this way which you have looked for in vain 
elsewhere, while your attention may be directed 
to certain new forms not thought of before. 
VALVES. 
Shells have valves just as books have leaves, 
and upon these valves you may read their life- 
histories. 
President Dwight, of Yale College, has a 
scholarly stoop in his shoulders, and seeing 
this and not meaning any disrespect, a little 
NewHaven girl said to her mother: ““Mamma, 
I think he is the s¢oofedest man I ever did see.” 
A funny little mollusk dwells in the harbor 
of Sydney, Australia, known by the name of 
Trigonia,(three-cornered), Aspecimen of the 
comb-like 7Jyigonia or TJ. pectinata, Lam.

Mr. Stutchbury, leapt overboard, clearing a 
ledge of four inches. 
The boys and girls interested in shells and 
living near San Joaquin River, Cala., will have 
no trouble in collecting fresh-water mussels 
(Unionidz) now,as the water is low and the river 
bed and the bottom of the large sloughs are 
fairly covered with them. Pearls of. fair color 
are found in these bivalves. 
Did you ever collect shells at Cape Henlopen, 
Delaware? We have, and at low tide have se- 
cured fine specimens of Bzsycon. Pyrula, 
Natica, Crepidula, Sigaretus, Petricola, Litto- 
rina, Soler, and many others too numerous to 
mention here, certainly enough specimens to 
keep your hands and heads busy for many eyen- 
ings and leisure days.
