EXPEBIMENTS IN THE BREEDING OF CERIONS. 



The Loggerhead Key Colony F. 



This colony consisted of 500 specimens imported in 1914 from 

 Bastian Point, Andros, the same locality from which the original 

 specimens of Cerion viaregis were obtained. The colony was placed 

 at the south end of Loggerhead Key, S. 24° W., from the long entrance 

 stake and S. 80° W. from the double stake which marks Colony E. 

 The colony was marked by a stake bearing a tag with the legend 

 "Bastian Point, Andros, 1914." 



In June 1915 the colony was thriving, although no young were 

 observed, and it was deemed best not to disturb the ground in order to 

 see if any were present. 



In May 1916 we gathered 300 tips of the first generation and these 

 were planted as Colony M. 



In July 1917 we measured, photographed, and marked 30 adults and 

 7 almost full-grown specimens and planted them with Colony M. 

 Table 6 gives the measurements. 



In January 1919 we gathered, measured, and photographed 100 

 additional first generation Florida-grown specimens of Colony F. 

 Table 7 gives the measurements; the photographs are shown on plates 

 22 and 23 and No. 85-100 on plate 24. 



The Loggerhead Key Colony G. 



The original planting of this colony consisted of 300 young specimens 

 gathered from Colony E in April 1914, some of which were figured on 

 plate 5, upper figure, and the 3 full-grown and 3 nearly full-grown 

 individuals on plate 3, top row of the 1915 report. This colony is 

 placed in a small meadow a little to the northeast of Colony E. It
