such useful physical attributes.

Their bridges may be divided into four types, namely: (1) A single
tree thrown across the stream, having either been blown down, and so
fallen across it accidentally, or been purposely placed across it by
the natives. (2) Two or more such trunks placed in parallel lines
across the stream, and covered with a rough platform of transverse
pieces of wood. (3) The suspension bridge. I regret that I am unable
to give a detailed description of Mafulu suspension bridges, but I
think I am correct in saying that they are very similar to those of the
Kuni people, one of whose bridges is described in the _Annual Report_
for June, 1909, as being 150 feet long and 20 feet above water at the
lowest part, and as being made of lawyer vine (I do not know whether
this would be right for Mafulu), with flooring of pieces of stick
supported on strips of bark, and as presenting a crazy appearance,
which made the Governor's carriers afraid of crossing it, though
it was in fact perfectly safe, and had very little movement, even
in the middle. I also give in Plate 65 a photograph taken by myself
[63] of a bridge over the St. Joseph river, close to the Kuni village
of Ido-ido, which, though a Kuni bridge, may, I think, be taken as
fairly illustrative of a Mafulu bridge over a wide river. [64] Plate
66 is a photograph, taken in Mafulu, of another form of suspension
bridge used by them, and adapted to narrower rivers, the river in
this case being the Aduala. (4) The bamboo bridge. This is a highly
arched bridge of bamboo stems. The people take two long stems, and
splice them together at their narrow ends, the total length of the
spliced pair being considerably greater than the width of the river
to be bridged. They then place the spliced pair of bamboos across
the river, with one end against a strong backing and support on one
side of the river and the other end at the other side, where it will
