crescentic cutting edge lengthening toward anterior into a spur 

 with sharp point and cutting edge. A similar compensating re- 

 curved spur projects from the bowed back of blade and in line with 

 it. This spur does not have a cutting edge, and is found in varied 

 forms on all of the head axes of the northern Luzon pagan tribes. 

 The wood handle is shod with ornamental overlay on crude silver 

 and brass repousse. An iron unornamented ferrule, 21 centimeters 

 (8.3 inches) in length, encases the hafting end of handle; a similar 

 shaped iron ferrule 8 centimeters (3.1 inches) long covers the proxi- 

 mal end. These iron collars are hourglass shaped, having longi- 

 tudinally concave surfaces. The ornamentation on the proximal 

 ferrule consists of series of encircling grooved bands; the spaces 

 betv/een the grooves are filled in with small, alternately circular and 

 diamond-shaped etchings. The surface of the wood between the 

 iron end pieces is filleted with 20 inset encircling bands of silver and 

 brass; each band has an average width of 0.5 centimeters and is 

 separated from the next filleted band by an equal distance. Alter- 

 nating with this series is another series of encircling bands of brass 

 repousse, each band 4 centimeters wide, and covered with geometric, 

 rectangular figures and small circular repousse disks. A strip cov- 

 ered with similar repousse work extends longitudinally the entire 

 length of the handle from one end ferrule to the other and serves 

 to hold the silver and brass filleted bands firmly in position by 

 means of brass rivets. 



Length of blade, 40.2 centimeters (13.8 inches) ; breadth of blade, 

 7.3 centimeters (2.9 inches) ; blade width in section at back, 0.3 

 centimeter; length of handle and blade, 57 centimeters (22.4 inches).

Head ax, Kalinga, nor-thern central Luzon. — Steel blade formed 

 in same shape as Cat. No. 303791 ; handle of plain hardwood polished 

 by use. At center of handle is hourglass depression fitted to the 

 hand, especially for the encircling forefinger and side of thumb. 

 Immediately behind is a laterally projecting spur of the wood handle, 

 wedge shaped toward the rear fitted to the ball of the hand but 

 flattened in front. This is characteristic of the w^orkmansliip of the 

 northern Luzon tribes in the manufacture of their head axes and 

 seems to be found noAvhere else. 



Length of blade from end of spur to tip of blade, 34.4 centimeters 

 (13.5 inches) ; blade section at back, 0.3 centimeter; width of blade, 

 7.7 centimeters (3 inches) ; length of handle and blade, 56.8 centi- 

 meters (22.4 inches). Collected by Miss Isobel H. Lenman. (PI. 10,
