Various authors, Mr. Dale’s second Excursion to trace the Helena River… (1833)
“ At a quarter before 8 o'clock, a.m. left Perth and forded the Swan River at the islands; at 9 proceeded in an E. direction over a sandy and thickly-wooded country, and in five miles crossed a swamp lying E. and W., and soon afterwards a rather extensive one to the S.E., which we again crossed to the S.W.; two miles and a half further passed a small one lying S.E. and N.W.; we continued our walk about the same distance of two miles and a half when we came to the dry bed of a stream, and continued along its banks till we reached the mountains, where we bivouaced at 4 p.m. ”
