.

PROPOLIS OR BEE GLUE. Whence it is obtained. Huber's experiment, 85. Its
use. Comb varnished with it. The moth deposits her eggs in it, 85.
Propolis difficult for bees to work. Curious use of it by bees, 87.
Ingenuity of bees admirable, 88.

CHAPTER VI.

POLLEN OR BEE-BREAD. Whence obtained. Its use. Brood cannot be raised
without it. Pollen nitrogenous. Its use discovered by Huber, 89. Its
collection by bees indicates a healthy queen. Experiment showing the
importance of bee-bread to a colony, 90. Not used in making comb. Bees
prefer it fresh. Surplus in old hives to be used to supply its want to
young hives. Pollen and honey both secured at the same time by bees.
Mode of gathering pollen, 91. Packing down. Bees gather one kind of
pollen at a time. They aid in the impregnation of plants. History of the
bee plain proof of the wisdom of the Creator. Bees made for man, 92.
Virgil's opinion of bees. Rye meal a substitute for pollen. Quantity
used by each colony, 93. Wheat flour a substitute. The improved hive
facilitates feeding bees with meal. The discovery of a substitute for
pollen removes an obstacle to the cultivation of honey bees, 94.

CHAPTER VII.

Fifty-four Advantages which ought to be found in an improved hive,
95-110. Some desirable qualities the movable comb hive does not pretend
to! Is the result of years of study and observation. It has been tested
by experience, 111. Not claimed as a perfect hive. Old-fashioned
bee-keepers found most profit, &c. Simplest form of hive, 112. Bee
culture where it was fifty years ago. Best hives. New hive is submitted
to the judgment of candid bee-keepers, 113.

CHAPTER VIII.

PROTECTION AGAINST EXTREMES OF HEAT, COLD AND DAMPNESS. Many colonies
destroyed by extremes of weather. Evils of thin hives. Bees not torpid
in Winter. When frozen are killed, 114. Take exercise to keep warm.
Perish if unable to preserve suitable degree of warmth. Are often
starved in the midst of plenty. Eat an extra quantity of food in thin,
cold hives, 115. Muscular exertion occasions waste of muscular fiber.
Bees need less food when quiet than when excited. Experiment, wintering
bees in a dry cellar, 116. Protection must generally be given in open
air. None but diseased bees discharge faeces in the hive. Moisture, its
injurious effects. Free air needful in cold weather, with the common
hive, 117. Loss by their flying out in cold weather. Protection against
extremes of weather of the very f
