Strange to relate, the South American seems to have a fondness for
stiff collars. Even in Corumba, the hottest place I have ever been in,
the native does not think he is dressed unless he wears one of these
stiff abominations around his throat. A light negligee shirt with
interchangeable or attached soft collars is vastly preferable. In the
frontier regions and along the rivers the pajama seems to be the
conventional garment for day as well as night wear. Several such suits
of light material should be carried--the more ornamented and
beautifully colored the greater favor will they find along the way. A
light cravenetted mackintosh is necessary for occasional cool evenings
and as a protection against the rain. It should have no cemented
rubber seams to open up in the warm, moist climate. Yachting oxfords
and a light pair of leather slippers complete the outfit for steamer
travel. For the field, two or three light woollen khaki-colored
shirts, made with two breast pockets with buttoned flaps, two pairs
of long khaki trousers, two pairs of riding breeches, a khaki coat cut
military fashion with four pockets with buttoned flaps, two suits of
pajamas, handkerchiefs, socks, etc., would be necessary. The poncho
should extend to below the knees and should be provided with a hood
large enough to cover the helmet. It should have no cemented seams;
the material recently adopted by the United States Army for ponchos
seems to be the best. For footgear the traveller needs two pairs of
stout, high hunting shoes, built on the moccasin form with soles. Hob
nails should be taken along to insert if the going is over rocky
places. It is also advisable to provide a pair of very light leather
slipper boots to reach to just under the knee for wear in camp. They
protect the legs and ankles from insect stings and bites. The
traveller who enters tropical South America should protect his head
with a wide-brimmed soft felt hat with ventilated headband, or the
best and lightest pith helmet that can be secured, one large enough to
shade the face and back of neck. There should be a ventilating space
all around the head-band; the wider the space the better. These
helmets can be secured in Rio and Buenos Aires. Head-nets with face
plates of horsehair are the best protection against small insect
pests. They are generally made too small and the purchaser should be
careful to get one large enough to go over his helmet and come down to
