Piper came in soon after the carts arrived, bringing a sad account of his interview with the natives. It appeared that, as soon as our party had proceeded to some distance from the lake, twelve men sprang from among the reeds armed with spears, boomerangs, etc., and when Piper accosted one of them, inquiring the name of the lake "I wont tell you," was the answer (murry coolah, i.e. very angrily). They then told him there was "too much ask" about him, and they blamed him for bringing the whitefellows there; adding that they did not like him; and an old man calling to the rest to kill him, for that he was no good, two spears were immediately thrown. These Piper parried with his carabine, and then instantly discharged it at the foremost, wounding him in the right jaw. The rest immediately disappeared among the reeds. The wounded savage fell, but Piper loaded again and killed him by another shot through the body. Such was Piper's story. I blamed him very much for firing at the wounded man, and I regretted exceedingly the result of his interview. I was besides most anxious to maintain a good understanding with these people. The spears used on this occasion were made of reed and pointed with bones of the emu; but we saw at their huts several heavy jagged ones of very hard wood for the purposes of fishing. The natives wore cloaks made of kangaroo skins. DISCOVERY OF THE JERBOA IN AUSTRALIA. A very curious and rare little quadruped was this day found by the two Tommies, who had never before seen such an animal. Its fore and hind legs resembled in proportion those of the kangaroo; and it used the latter by leaping on its hindquarters in the same manner as that animal. It was not much larger than a common fieldmouse, but the tail was longer in proportion to the rest of the body even than that of a kangaroo, and terminated in a hairy brush about two inches long.* (Plate 29.) (*Footnote. This appears to be a species of Jerboa, thus for the first time seen by us in Australia. My friend Mr. Ogilby has described this animal in the Linnean Transactions from my drawing and descriptions; the specimen itself having been deposited in the Australian Museum at Sydney. Dipus mitchellii, D. plantis subpentadactylis; corpore supra cinereo-fusco, subtus albido; auriculis magnis, cauda longissima, floccosa. Linnean Transactions volume page 129.) We also discovered a beautiful new species of the Cape genus Pelargonium, which would be an acquisition to our gardens. I named it P. rodneyanum* in honour of Mrs. Riddell at Sydney, grand-daughter of the famous Rodney.
