Mother wasps and hornets only survive Winter. Queen, process of rearing, 66. Royal cells, 67. Royal Jelly, 68. Its effect on the larvæ, 69. Swammerdam, 70. Queen departs when successors are provided for. Queens, artificial rearing, 71. Interesting experiment, 72. Objections against the Bible illustrated, 73. Huish against Huber, 74. His objections puerile. Objections to the Bible ditto, 75. CHAPTER IV. COMB. Wax, how made. Formed of any saccharine substance. Huber's experiments, 76. High temperature necessary to its composition, 77. Heat generated in forming. Twenty pounds of honey to form one of wax. Value of empty comb in the new hive. How to free comb from eggs of the moth, 78. Combs having bee-bread of great value. How to empty comb and replace it in the hive, 79. Artificial comb. Experiment with wax proposed, 80. Its results, if successful. Comb made chiefly in the night. 81. Honey and comb made simultaneously. Wax a non-conductor of heat. Some of the brood cells uniform in size, others vary, 82. Form of cells mathematically perfect, 83. Honey comb a demonstration of a "Great First Cause," 84. CHAPTER V. 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.
