These ladders have at best but little stability, as they consist of two uprights, careless about the coincidence of the holes, with bars poked loosely through and left to fall out or stay in as they choose, the former being the prevailing choice. One of the ladders happened to be firmer than the generality of its kind; but, unfortunately, its legs were of unequal lengths, and so it turned round with one of my sisters, leaving her clinging like a cat to the under side. When the bars are sufficiently loose, a difference of a few inches in the lengths of the legs is not of so much importance.
