Together the above gives a 95$ complete nest count for

Tht 30 eggs from the Casuarin^ part of the colony were 
all checked for stage of incubation by flotation. Of 
the 30 1 ( ) was fresh, 1 ( ) was very slightly 
incubated, 6 ( ) were slightly incubated, 7 ( ) 
were moderately incubated and 15 ( ) were heavily 
incubated. The data thus indicating a nice curve of 
progress in laying in this colony when title small and 
medium chicks are taken into account. The high tail 
for large chicks probably results from the ^postulated 
ff wave laying effect” that appears to occur in Black 
Noddies on the Leeward (and perhaps othef % Xlslands. 
Culmen lengths were measured on the small downy chicks 
(those recently hatched and too small tO band) and 
wing lengths were taken as well. Culmen lengths were 
measured to the nearest tenth of a mm. and wing lengths 
were tpken to the nearest mm. Hopefully this will allow 
fairly exact aging of these birds to allow an accurate- 
calculation of laying date©* These measurements we;res
