In the second place, I could not but see that their dwellings are constructed on the very minimum of base, propping each other, as emblematic of the mutual support obtained by the republican system, and seeking their development in height for the want of breadth; a singularity of customs that I did not hesitate at once to refer to a usage of living in trees, at an epoch not very remote.

In the third place, I noted, instead of entering their dwellings near the ground like men, and indeed like most other unfledged animals, that they ascend by means of external steps to an aperture about half-way between the roof and the earth, where, having obtained admission, they go up or down within the building, as occasion requires.

This usage, I made no question, was preserved from the period (and that, too, no distant one), when the savage condition of the country induced them to seek protection against the ravages of wild beasts, by having recourse to ladders, which were drawn up after the family into the top of the tree, as the sun sank beneath the horizon.

These steps or ladders are generally of some white material, in order that they may, even now, be found in the dark, should the danger be urgent; although I do not know that Bivouac is a more disorderly or unsafe town than another, in the present day.

But habits linger in the usages of a people, and are often found to exist as fashions, long after the motive of their origin has ceased and been forgotten.
