Outside the total zone the eclipse will be of necessity partial, but 
all over the Colony it will be well seen, as almost at all places nine- 
tenths at least of the sun’s disc will be obscured. It has already been 
stated that the city of Grahamstown is just on the borderland of 
totality. No doubt October 1, 1940, will be a general holiday when 
the day comes, so that the citizens of Grahamstown may view the 
only total eclipse of the century visible in the Colony.

(7) Annular Eclipse of January 14, 1945. 
The central shadow of this eclipse will pass on to the earth at a 
point where the Division of Woodhouse is turning to the sun’s light. 
As the South Pole is turned to the sun, and the parallels of latitude 
accordingly slope upwards, the shadow will move downwards through 
the Colony. Its path, therefore, lies through Woodhouse, Tembuland 
and the Transkei. 
All places east of a line joining Dordrecht with Algoa Bay, have the 
maximum eclipse just at sunrise, as also Pondoland, Griqualand East, 
Basutoland, and Natal. West of this district the maximum eclipse 
is over before sunrise, and will therefore be of little importance. All 
along the central line, or, rather, within the central zone, which includes 
Dordrecht, Indwe, Lady Frere, Cala, Engcobo, Tsomo, Clarkebury, and 
Idutywa, the rare phenomenon will be witnessed of a sun rising fotally 
eclipsed. For although the eclipse is theoretically annular, the ring of 
light seen round the moon’s disc is so small, and will be so faint, that - 
practically the eclipse is total. The duration of central eclipse is only 
forty-five seconds, and some idea may be formed of the velocity with 
which the dark shadow sweeps over the earth by observing from the 
tables that it takes about fifteen seconds to pass from Dordrecht to 
_ the sea, equivalent to a velocity of ten miles a second. 
The zone of annular eclipse is narrow, being only forty miles wide.
