134 from the mainland, the one by the Wando River, the other by Wappoo Creek; while Sullivan's Island, where stand Fort Moultrie and other Rebel batteries, corresponds almost precisely to Morris Island, both being low and sandy, and being, as it were, bent inland from the sea, with sharp points looking toward the city, their convex shores forming a rounded entrance to the harbor. Extending southward from Morris Island, and separated from it by Lighthouse Inlet, is Folly Island; and in exact correspondence to the latter, north of Sullivan's Island, and separated from it by Breach Inlet, is a similar sand-ridge called Long Island. But now occurs a difference; for while between Long and Sullivan's Islands and Christ's Church Parish is an immense salt marsh intersected by creeks, but presenting an unbroken surface, in the midst of the corresponding marsh between Morris and Folly Islands and James Island is a group of low wooded islands, the largest of which lies opposite the upper or north end of Folly Island. To this no name is given on the maps, nor is it even distinguished from the marsh. It is, however, completely surrounded by water; and, though this is in the form of creeks neither wide nor deep, yet the peculiar softness of the mud, and the absence of any landing-place except upon the side toward Folly Island, render it almost inaccessible.

To this narrow strip of land, not three miles in length, was given the name of Long Island,—perhaps by our own troops, who knew nothing of an island of the same name north of the harbor; and in case it is found that no other name belongs to it, we may properly avoid a confusion, and christen it Spider Island, in honor of the remarkable insects for whose especial benefit it seems to have been made, and which, with the exception of the mosquitoes, are its sole inhabitants.

As was said, the first spider was found on Folly Island on the 19th of August, 1863: it was also the last there seen. During the summer of 1864, many were found on Long Island (so called); and when, in the spring of 1865, our regiment was encamped on James Island near Wappoo Creek, it was toward Long Island that all my attention, so far as concerned spiders, was directed.

But first, as a bit of collateral history, and to show how easily and how far one may go astray when one of the links in the chain of argument is only an inference, let me relate that, while riding over James Island, I observed upon trees and bushes numbers of small brown bags, from half an inch to an inch and a half in diameter, pear-shaped, and suspended by strong silken cords. The bags themselves were made of a finer silk so closely woven as to resemble brown paper, and, when opened, were found to contain a mass of loose silk filled with young spiders to the number of five hundred or more. In certain localities, especially in a swampy field just outside the first line of Rebel works, they were quite abundant. I had soon collected about four hundred of them, which, by a moderate estimate, contained two hundred thousand little spiders,—quite enough, I thought, with which to commence operations. But one hot day in June I placed them all on a tray in the sun. I was called away, and on my return found my one fifth of a million young spiders dead,—baked to death.

Prior to this catastrophe, however, I had become convinced that these were not the spiders I sought. Indeed, my only reasons for thinking they might be were, first, the abundance of these cocoons in a locality so near Long Island; and, second, my own great desire that they should prove the spiders I wanted. The young spiders, it is true, did not at all resemble their supposed progenitors, as to either shape, or color, or markings; yet all of these evidently changed during growth, and would not of themselves disprove the relationship.

One day in April, however, a cocoon was found in a tree on James Island, of a very different appearance from the
