of the honey material. The green are of two species. "The 
one also furnishes juice to the bees, but in Jess quantity — 
than the preceding. ‘The other species of green pucerons, 
are useless to our precious insects, and pernicious to the 
trees. This last kind ordinarily finish their career, by en- 
veloping themselves in the leaves of the trees on which 
they live, and which they crisp and destroy. “7 apes 
Such are the new resources for the subsistence of bees, — 
which were unknown to us, before the observations of M. 
Boissier de Sauvages, the reading and study of which, have — 
produced mine. Other amateurs of the culture of bees, 
and among them, M. Rosi, merchant of Redon, have also 
begun to make their individual remarks on this part of our 
natural history. M. Rosi was led to it, by seeing some. 
stones bedewed with a viscous matter, which gave them a 
shining appearance, and which attracted a great many 
bees, near a slate quarry, which he was working. This 
viscous matter fell from an oak, standing near his quarry, 
on some refuse slate. He attributed it, he said, to the 
transudation of the leaves of the tree. This learned ama- 
teur made a strict examination, and found on the tree, a 
family of pucerons. He satisfied himself that the substance 
sucked by these insects through the bark of the tree, and 
dejected in excrements, was not yet honey as it passed out 
of their abdomen. It is however a proper material to pro- 
duce honey, but it must be first elaborated in the stomach 
of the bee. ste

CHAPTER XIX. 
OF ANIMALS AND INSECTS ENEMIES OF BEES. 
_ Bees have a great many enemies, because they are labo- 
rious, and live in plenty. In winter, and often in summer, 
they are besieged by other insects, who never have any 
provisions, but what they procure from day to day, by 
robbery. Moles, rats, and the different kinds of mice, are 
not the most dangerous when the bees are lodged in wooden 
boxes, the openings of which in winter, do not present an 
entry sufficiently large for the passage of these animals. 
In this season, the openings should be no larger than suffi- 
cient for the passage of one or two bees at a time. In 
spring and summer, the bees are too vigorous to fear any 
thing from that class of enemies. It is known that these
