"My first discovery of ] their' existence in Otago was accidental.; Rather more than two years ago, I was riding slowly through an English grass paddock in our Awamoko Estate,' ,near Daniai-u, ' with our; manager. On a bare patch'of ground, my eye accidentally rested upon a very large spider. Attracted by its size, I kept steadily looking at; it, when suddenly, as it by magic, it dis appeared totally. Iri my astonishment,' I exclaimed: 'Well, Little, did you ever hear of a spider that could fly, for I could take my oath that, I saw;an. immense spider' down on that bare.'patch just now, and it dis appeared in a moment, and' if it did not fly away, it can't have gone Anywhere,else.' So, I got off my horse arid handed, him the reins, so ; as to carefully examine the ground, which was very dry, and dusty.. My suspicions that the spider had rolled itself up in the dust were soon confirmed by observing that' the .eai-thw'as a little raised or bulged up at one part,' and so I took my knife to turn hinn out' of hia dirt heap. Judge of my surprise arid delight when, no sooner had I applied the point of my tnife, when up sprunsjabeautiful trap-door, revealing a large hole going right down , intd the earth, lined with beautiful white silk that shone in the sun and that covered over the inside of the 'door, arid formed a clever and remarkably good I hinge. I had' no doubt now where the spider Lad gone, but; having no tools with us we' could not .dig Jfc.'.ouV". I examined' this. strange ' novelty some time, lifting up' ; the wonderful door, and ad miring the exactness with which it fltted, the .perfect mobility of' the hinge, ; the; spring which immediately shut down on slip ping from the knife,, and the marvellous adap-, "tation of the outside of )the lid to the existing conditions surrounding it.,,, It was literally pepjiered on the outside with loose soil, exactly the same as that afoundjsp as ,to.defy:detection by anyone unacquainted .with the way of. find ing such nests..' .In' fact, although J had'care fully marked several. things near by, so. as to find it again, when I returned Math a spade I cnuld not find it, and never, afterwards came upon this particular nest.
