[Various (1967)] one shoulder is sharply cornered and the other is rounded. Why it did not come into vogue sooner to round both shoulders or why it came into vogue when it did will probably never be ascertained, but it did come into vogue eventually, to establish a discernible variety. That it was in vogue quite early is best illustrated by the specimen pictured in Ritchie (1965), Plate 14, no. 32, Projectile points of the Lamoka phase and type. Phase 1: PHASE DESCRIPTION THE HUDSON PLUG STEMS: The blade is narrow, tight-shouldered, lenticular, or conical in cross-section and outline. The stem is thick and peg-like or knobby, apparently for a tendon insertion into the shaft end. The base is blunt. Variety: The Hudson Half and Half. These are asymmetric points, with one side developed into a shoulder and the other side either more or less straight, without shoulder, or excurvate. Locale Sub-variety: The Slug. The blade is short and blobby and the stem contracts toward the base. A locale sub variety, it is one which occurs in only a very No. 39, March 1967 9 few specimens, but on several sites so that it seems to have been made only by a very limited number of craftsmen. Phase 2: THE CROTON BIT STEMS. The blade is as in the plug stems but the stem is thinned down like a screw-driver bit, as though for slotting into the shaft end.
