forming a line. The extreme wire, A, connected with the 
inside of the jar, and the other extreme, B, with the out- 
side, show the circuitous route of the influence after the 
knob of the jar was touched. The report was simultaneous, 
but owing to the wires of two of the interior holes crossing 
and touching each other, they did not explode. e roc 
was cracked but the portion was not thrown off. The gen- 
tleman thinks that if these two holes had exploded, the full

loose cork, having little hold of the rock. I advised him to 
fill up with sand, in Jessop’s manner, and, from a trial made 
to-day, it promises to answer. The iron wire, being a much 
better conductor than sand, the latter did not seem to divert 
the influence at all: He has gone to the island to prepare a 
more magnificent experiment, the result of which I shali 
hasten to communicate to you. 
12. Mode of decoying wild pigeons in New England.—The 
flight and stool pigeons, as they are called, are prepared by 
passing a thread through the edges of both their eyelids whick 
are thus closed—their legs are booted, and the flights, being 
fastened to long strings, are thrown into the air and fly as 
far as they are permitted, while the stool pigeon is tied to a 
narrow board, which, at the end where the bird is fixed, rises 
and falls, and both kinds of decoy, by the flapping of their 
wings, draw the attention of the passing flocks of wild pig- 
eons, which are thus made to alight, on prepared ground, 
within reach of the concealed spring-net, or on a long pole, . 
zg can but recommend extreme caution, in using detonating silver, 
especially in such quantity as toform one tenth of the charge.— Editor.
