This differs considerably from the diurnal curves of velocity for Kimberley 
and East London in that while these two last show the greatest velocity 
for the day between XIII. and XIV. o'clock, at Lourengo Marques the 
maximum velocity comes in the late afternoon. A curious feature — not 
altogether unknown elsewhere, however — in the diurnal curve for the 
latter place is the fall in velocity in most of the months at 11 a.m. 
Table 3 shows the prevailing winds during each quarter of the year. 
It shows the number, of hours in each quarter in which the vane was 
pointing in any given direction.
