A MINIATURE BARBADOS. 89 



oozes in Cuba have been correlated with the oceanic series 

 of Barbados, and also with like deposits in Jamaica. 



Whether similar radiolarian oozes would be found 

 beneath the deposits aheady exposed on Swan Island is, 

 of course, a matter of conjecture ; but it would not require 

 a great effort of the imagination to picture the time 

 when in future ages, Swan Island may be uplifted to much 

 greater heights than its present level, and when a very 

 similar series of rocks will have been exposed as obtains 

 on Barbados at the present day. 



Moreover, in this hypothetical upheaval, we can foresee 

 the formation, on a smaller scale, of exactly the same 

 series of coral terraces, derived from a sequence of fringing 

 reefs, as has occurred on Barbados. It is rather curious 

 also to ncte, as bearing on our comparison of the two 

 islands, that just as in the process of upheaval which rook 

 place in Barbados, that island, at one period, consisted 

 of two separate portions divided by a channel, at the 

 bottom of which ^ rew reef-building corals ; so we see 

 exactly the same conditions in the twin nature of the two 

 Swan Islands at the present day. 



It is also interesting to note the occurrence of the red 

 clay-like shales, which we have already referred to as 

 occurring at the foot of the low escarpment at the east 

 end of the western island ; for red clays are found in places 

 in Barbados lying between the white oceanic earths and 

 the coral capping.
