is everywhere, so was Russula. It 
also came to light. A correspond-

this, and particularly notes the

between 9 and 10 p. m., so that

Ph. Fuliginosa. — May 28. 
Larvae abundant in autumn. Can 
there be a second brood ?

Larvae abundant in autumn. 
Came in numbers to light. 
Sp. Lubricf^peda. — June 21. 
Not so plentiful as the last. 
Larvae spun this year about Sep-

wing in the evening. Very like

EXTRACTS. 
Sagacity of the White Ant. 
— In nothing is the ingenuity of 
these little insects more remark- 
ably displayed than in the ex- 
pedient to which they frequently 
resort to cross a little stream on 
the sand beach after a shower of 
rain. Sometimes their train is 
cut in two by one of these little 
streamlets. To plunge into it 
singly, they would soon be swept 
away by the rush of the current. 
They come to the edge of the 
water, raise their antennae, point 
them from one direction to ano- 
ther, as if they were taking a 
scientific view of all the dangers 
of the crossing. They wander up 
and down the stream with the 
greatest uneasiness, and finding 
no other way to cros.s, form them- 
selves into a compact knot or raft 
of a dozen or more, and launch 
themselves upon the stream. They 
have, by previous observation, 
made sure that they would strike 
a projecting point or bluff on the 
opposite shore, and. not be carried 
by the current into the main river. 
The moment they touch the other 
side, they use their claws like 
anchors, and hold on until the 
whole company disengage them- 
selves and march ofi" in single file 
in the track of those that have 
preceded them. I have watched 
them for hours together, and have 
seen raft after raft of these little 
creatures go over in safety, when, 
if they bad attempted to get across 
singly, they would all have been 
swept into the river. — Wilson's

Curious, if True. — A curious, 
and we must add very apocryphal, 
circumstance, is said to have oc- 
curred in the silk factory of M. 
Garibaldi, at Cremona, which has 
caused some discussion among the 
Italian journals. It is positively 
staled that, in that factory, a 
quantity of silk-worms, instead of 
forming the cocoon as usual, 
actually wove a kind of silk rib- 
bon, of the breadth of an inch, 
and the length of upwards of 
twelve feet. In the course of the 
denials and assertions exchanged 
on this matter, it has been elicited 
that a similar phenomenon, only 
on a much larger scale, took place 
at Alessandria in 1836, in the silk 
factory of Dr. Grille, where the 
silk-worms wove a ribbon two 
inches broad and upwards of sixty
