EXPLANATION OF PLATES. 
Plate I. Examples of houses in Belize. The water receptacles are characteristic. 
Observe the kerosene tins in Fig. i, and the planks, etc., for conducting the water 
to the barrels. Note the stepping planks and the littered condition of the yard in 
Fig. 2. Observe that the house in Fig. i is only raised about i ft. above the sodden 
ground. 
PLATE II— Other examples of water receptacles. Note that the houses are raised. 
Plate III. Fig 5 shows how some of the public cisterns are treated. The water from the 
roof is conducted to the cisterns beneath the roof. Observe that they are close to 
the ground, which is a mistake. 
Plate IV. The appearance indicated in plate is characteristic. Marsh is everywhere, 
and it is difficult to get to many of the houses. 
Plate V.— Similar condition. The houses in Fig. 10 are well raised, 
Plate VI. — In Fig. 11 there is enough water to float the canoe. In this state it is 
impossible to do any washing in the yard, and the water receptacles often stand in 
the dirty water. Fig. 12 shows a very badly placed latrine. 
Plates VII. and VIII. show typical examples of street side drains. Owing to the 
general dead level of the town there is no appreciable fall in them. They should be 
either filled in or replaced by properly constructed canals. They now breed 
Anopheles. 
Plate IX. — Fig. 17 shows the old canal, it is very useful, does not breed Anopheles, takes 
away the night soil. A second line of canals should be constructed on similar 
lines. Fig. 18 shows how the end of a street may be blocked by buildings. 
PLATE X. — I he two figures show the position of Quarantine station in a marsh. 
PLATES XL, XII. AND XIII. — These are a series of photographs kindly furnished tome 
by Dr. White, in charge of the Yellow Fever Campaign in New Orleans in 1905, and 
represent the various operations in Yellow Fever prophylaxis.
