. Fig. 14. Diagram illustrating the ratio of northerly to southerly drift (respectively above and below base-line) at different distances from the coast. The data are plotted separately for Peru (uppermost) and for Chile (centre); and in combination for the west coast as a whole (lower- most). The drift, expressed as miles per day, represents the mean drift of the ship in a direction parallel to the coast; and is computed by dividing separately the total amounts of the drift in each direction by the total number of observations in both directions. 1 1 ^JC1I^TH PERU 1 PERU 1 1 4 1 4-5 1 6 \y\ a
