pound.

The molten slag, as it runs from the furnace, may be discharged into
tanks of cold water, which will pulverize or granulate it, making it
like fine sand, or as it pours over a runner, through which it flows,
if struck with a forcible air or steam blast it will be spun into fine
thread-like wool.

The furnace once lighted and started may be kept running day and night
continuously for days, months, or years, if desired; but if it becomes
necessary to stop at any time, the tuyere pipes may be removed and the
holes all stopped with clay, so as to entirely shut off the supply of
air, and it will then hold in fire for many days, and will be in
readiness to start again at any time the pipes are replaced and the
blast turned on.

This furnace is the invention of Mr. Henry R. Foote, of Stamford,
Conn.

AN ANCIENT GREEK VASE.

The vase shown in the accompanying engravings must not be classed with
ordinary ceramic ware, as it is a veritable work of art. It is the
celebrated cup of Arcesilaus, which is preserved in the collection of
the library of Richelieu street after having figured in the Durand
Museum. It was found at Vulsei, in Etruria. It was made by a potter of
Cyrene, the capital of Cyrenaica, founded by Greeks from the island of
Thera. It is remarkable that Cyrene, removed from the center of
Grecian manufacture, should possess a manufactory of painted vases
from which have come so many works of art. The traveler, Paul Lucas,
discovered in the necropolis of Cyrene, in 1714, many antique vases,
both in the tombs and in the soil. One of them is still preserved in
the Museum at Leyden. The Arcesilaus, who is represented on this vase,
is not the celebrated skeptical philosopher of that name; it is
Arcesilaus, King of Cyrenaica, who was sung by Pindar, and who was
vanquished in the Pythian games under the 80th Olympiad (458 years
B.C.).

The height of this vase is 25 centimeters, its diameter 28
centimeters. The paste is very fine, of a pale red. It is entirely
coated with a black groundwork, which has been generally re-covered
with a yellowish white clay, baked on.

According to M. Brongniart, this piece has been subjected to the
baking process at least two or three times, thus indicating that the
ceramic art had made considerable progress in Cyrene even at that
remote epoch.

The following description of this vase is given in the catalogue of
the Durand Mu
