The Life of the Spider

dispersal presents no difficulties. Each emigrant leaves at his own good time and travels as suits him best.

My devices have changed these conditions somewhat. My two bristling poles stand at a distance from the surrounding shrubs, especially the one which I planted in the middle of the yard. Bridges are out of the question, for the threads flung into the air are not long enough. And so the acrobats, eager to get away, keep on climbing, never come down again, are impelled to seek in a higher position what they have failed to find in a lower. The top of my two bamboos probably fails to represent the limit of what my keen climbers are capable of achieving.

We shall see, in a moment, the object of this climbing-propensity, which is a sufficiently remarkable instinct in the Garden Spiders, who have as their domain the low-growing brushwood wherein the nets are spread; it becomes a still more remarkable instinct in the Lycosa, who, except at the moment when she leaves her mother's back, never quits the ground, and yet, in the early hours of her life, shows herself as ardent a wooer of high places as the young Garden Spiders.
