relatively broader than in the Bagobo. The forehead is
usually high and full, but in about one-third of the individuals
measured it was moderately retreating, while in the same proportion the
supra-orbital ridges were quite strongly marked. In other features, as
well as in hair form, eyes, body form and color, this people conform to
the description given of the Bagobo (Plates XLII-XLVIII).

[56] Measured from the chin to the hair of the forehead. The greater
part of this tribe live far back in the rugged mountains which form the
watershed between the Cotabato valley and the Gulf of Davao. Travel
through that district is entirely on foot, and is principally along the
water courses, so that in going from place to place a person is
continually crossing the stream. From time to time dim trails, scarcely
worthy of that name, lead from the river's bank almost perpendicularly
up the mountain-side or to the summits of high hills, where will be
found one or two frail houses (Plate XLIX). The dwellings are never in
large groups, and more frequently each house is by itself. From one
habitation it is possible to look across the hills and see many others
at no great distance, to reach which would necessitate a descent of
several hundred feet and an equal climb up to each.

There is considerable variation in the architecture of the dwellings but
the following description of the home of Datu Dialum, on the headwaters
of the Ma-al river, will give the general plan of all.

Small hardwood poles about twenty feet in length formed the uprights to
which the side and crossbeams were lashed, while in the center of each
end beam smaller sticks were tied to form the king posts. From the ridge
pole small timbers extended to the side beams, thus forming the
framework on which the final topping of flattened bamboo was laid. This
roof was of one pitch and at the sides overhung the walls by about a
foot. Twelve feet above the ground other poles were lashed to the
uprights and on these rested the cross timbers of the floor, which in
turn were covered with broad strips of bark. The side walls extended
between the floor and the beams, but in no place did they extend up to
the roof. Entrance to the dwelling was gained by a notched log.

Once inside the house the arrangement impressed one as being similar to
those of the Bagobo. Just above the door, and again in the far end of
the room, poles were laid across the beams to form the floors of lofts
