I have already made a first Report on the Springvale Fo.ssils 
which has appeared in the Proceedings of the Societ}’ for No- 
vember 1910, page 447. Under the Auspicesof the Agricultural 
Societ}" I visited the Springvale quarry, on the i6th November, in 
compaii}' with Dr. Fredholm and others. The Road Officer, Mr. 
Todd, who is in charge of the quarry gave us every as.si.stance. 
This enabled me to glean some further information. The depo.sit 
is one of remarkable richness in fossil shells and the variety of 
species found in the one place is quite astonishing. The shells 
are generally w’ell-preserv'^ed, but their fragility is such that 
many beautiful specimens go to pieces on handling or in trans- 
port. I found that the difference in color of different samples of 
Page 2 
the bed, wdiich I had previously noticed, was due merely to oxida- 
tion, the portions of the bed near the surface being converted to a 
reddish-brown color, while the inner parts were gray. This is 
quite a common or rather almost universal change produced by 
the access of air and Water. 
The quarry is situated on the side of a low hill, one of the 
lateral spurs of the Montserrat range. It is in a cacao wood and 
the neighbouring surfaces are covered wdth vegetation, so that it 
could only be with axe, pick and spade that further exploration 
could be made. I should think it likely that the deposit w'ould 
be found to extend to a considerable distance. The material 
w'ould he useful on a soil destitute of lime, but the soils in the 
immediate neighborhood are fairl)^ supplied with this substance.
