My dear Dr. Holland:

In answer to a request recently made by you, I will state what material from the Jensen Dinosaur Quarry it would seem expedient to work out as soon as possible.

No. 145 (Field No.) is a medium-sized sauropod Dinosaur. It consists of the Dorsals, Sacrals, Eleven or twelve cervicals and about 25 Caudals. It is apparently different from anything else we have in the quarry. Possibly it is of the Morosaurus-type. I think it would work out easily and be a good specimen.

No. 160 has been worked out in relief from the end of the tail to about the 8th Dorsal. There are still seven or eight blocks, unopened, which contain the remainder of the dorsals, the greater portion of the neck and some limb-bones. These will require much care and skill as the bones will undoubtedly be found to be, in part, very frail, so that much hardening will be required.
