When a seal is seen, the siatko is taken from a little leathern case, in which, when out of use, it is carefully enclosed, and attached by its socket to the point of the spear; in this situation it is retained by bringing the allek tight down and fastening it round the middle of the staff by what seamen call a “slippery hitch,” which may instantly be disengaged by pulling on the other end of the line. As soon as the spear has been thrown, and the animal struck, the siatko is thus purposely separated; and being slung by the middle, now performs very effectually the important office of a barb, by turning at right angles to the direction in which it has entered the orifice. This device is in its principle superior even to our barb; for the instant any strain is put upon the line it acts like a toggle, opposing its length to a wound only as wide as its own breadth. The _āklĕak_, or _aklēēgă_, used for the large seal, has a blown bladder attached to the staff, for the purpose of impeding the animal in the water. The weapon with two long parallel prongs of bone or iron, obtained from the natives of the Savage Islands, these people also called _akleak_, and said it was for killing seals. The third and largest weapon is that called _katteelik_, with which the walrus and whale are attacked. The staff of this is not longer but much stouter than that of the others, especially towards the middle, where there is a small shoulder of ivory securely lashed to it for the thumb to rest against, and thus to give additional force in throwing or thrusting the spear. The ivory point of this weapon is made to fit into a socket at the end of the staff, where it is secured by double thongs, in such a manner as steadily to retain its position when a strain is put upon it in the direction of its length, but immediately disengaging itself with a sort of spring, when any lateral strain endangers its breaking. The siatko is always used with this spear; and to the end of the allek, when the animal pursued is in open water, they attach a whole seal-skin (_hŏw-wūt-tă_), inflated like a bladder, for the purpose of tiring it out in its progress through the water.
