"Washington April 15-1936 Left Dr. on a fine morning at 10:00 and will arrive at New Haven at 4 P.M. The last two days has been co- plete with new information among the paleontologists of the U.S.N.M. and J.S.G.S. Cooper is the one with most new correlations on the Middle Devonian and I hope he will carry his correlations into full fruition. He wants to place the Sturgespokes fauna between the Onondaga and the Hamilton. This is radical and appears to be a- gainst all former information. He tried to see himself in the Delaware of Ohio and elsewhere to substantiate this, I must have to look into this".
