Show Sends Fossil Specimens From Leamington Herewith enclosed you will find a camera picture of a colony of coral, which I think may be of interest in-terest to you. It was taken by my son while on a visit here at Christmas. Christ-mas. He just sent it to me from Honolulu. This coral is partly replaced with silica. It is in the face of a lime rock ledge on the Gibson Mountain Mount-ain about 1 1-2 miles north of here. It is about two feet across. At may be seen from the picture, pic-ture, this coral branches downwards. down-wards. Wouldn't this indicate that the stratum in which it is found has been overturned? We have found a number of these specimens in the same formation for-mation and they are all inverted. We call it "upside down" coral. There are many other interesting interest-ing fossils to be found along the Gibson and just recently, while on a hike across the river, I ran on to some curious fossils which I am unable to identify, but I think they may be porifera. I would like to have your opinion regarding them. There is also an interesting in- I trusion of felsite with slickenside jointing near where these latter were found. My hobby is the study of rocks and collecting concretions, and I run on to new surprises continually. continual-ly. Very truly yours, Samuel P. Jensen (The photo shows downward branching stems which is unusual. I gathered fossils there some years ago, the species Archimedes, in coral growth, evidencing that this area was once covered by the Pacific Pa-cific Ocean. Thanks for the photo and information. F.
