EXPERIMENTS IN THE BREEDING OF CERIONS.

marked the original planting. They were in the southeast corner of 

 the same meadow in which the original planting was made, in condi- 

 tions apparently identical with those prevailing in the territory occu- 

 pied by Colony A. The place is marked with a stake bearing the 

 legend "Cerions X." 



On June 28, 1915, we recovered 122 full-grown and 17 immature 

 specimens from this colony; these we measured, marked, photographed, 

 and planted in a new location as Colony J, which see. Their measure- 

 ments are given in table 23 and their photographs are shown on plates 

 38 to 41. 



In May 1916 we gathered 73 adults of the first generation of Florida- 

 grown individuals. Measurements of these are given in table 24, the 

 specimens are figured on plates 42 and 43.

LOGGERHEAD KEY COLONY C. 



On June 27, 1914, we planted 100 marked immature specimens of the 

 first generation of Florida-grown individuals from Colony A, on the 

 west side of the path between the laboratory and the lighthouse, about 

 135 feet south of the stake marking Colony A. This planting was in 

 the northeast corner of a large meadow bearing a tag with the legend 

 "Cerions Y."
