Longitude 128° 34', encountered the Alert, manned by a queer and evil-looking crew of Kanakas and half-castes. Being ordered peremptorily to turn back, Capt. Collins refused; whereupon the strange crew began to fire savagely and without warning upon the schooner with a peculiarly heavy batter of brass cannon forming part of the yacht’s equipment.
