In our study of the Geology of Trinidad, we must proceed 
step b3^ step, but the general cultivation of elementary geology 
would facilitate a more rapid progress. Everyone who digs a 
quarr\’ or makes a boring should preserve samples of the mater- 
ials, even the least likel}’ looking, found or passed through, and 
submit them to those who have the means of scientific examina- 
tion. We have now made a real and important advance in our 
knowledge of the Tertiaries ; first, from the information gained 
from the Manjak Mines and secondly, from the discover}' of the 
vSpringvale fossils. These give us the means of effecting some 
improvement upon our previous classifications, and to speak with 
more certainty upon .some points, but we have a long wa}' to go 
before reaching finalitj’, or an\-thing like it. 
I make these remarks prefatory to a report on a collection of 
shells found at Spring^■ale, near Couva, in this Island. The.se 
fo.ssils have been confided to me by the Agricultural Society for 
examination. 
The two kinds of matrix adherent to these fossils seem to 
indicate that they come from two beds, one a ferruginous shelly
