Having satisfied herself for the time with observing the workers coming and going, she went around to the white clover-field to see the process of gathering the honey. She had long since learned that bees while at work are harmless, unless so cornered that they sting in self-defence. Sitting on a rock at the edge of the clover-field, she listened to the drowsy monotone of innumerable wings. Then she bent her glass on a clover head, and it grew at once into a collection of little white tubes or jars in which from earth, air, and dew nature distilled the nectar that the bees were gathering. The intent workers stood on their heads and emptied these fragrant honey-jars with marvellous quickness. They knew when they were loaded, and in straight lines as geometrically true as the hexagon cells in which the honey would be stored they darted to their hives. When the day grew warm she returned to the house and read, with a wonder and delight which no fairy tale had ever produced, John Burroughs's paper, "The Pastoral Bees," which Webb had found for her before going to his work. To her childish credulity fairy lore had been more interesting than wonderful, but the instincts and habits of these children of nature touched on mysteries that can never be solved. At dinner the experiences of the apiary were discussed, and Leonard asked, "Do you think the old-fashioned custom of beating tin pans and blowing horns influences a swarm to alight? The custom is still maintained by some people in the vicinity." "I doubt it," said Webb. "It is no longer practiced by scientific bee-keepers, and yet it is founded on the principle that anything which disconcerts the bees may change their plans. It is said that water or dry earth thrown into a whirling swarm will sometimes cause it to alight or return to the hive."
