January 12, 1916 Mr. Earl Douglass Jensen Utah My Dear Dougalss;- Under date of January the 8th I have received from the Secretary of the Interior a permit allowing the Carnegie Museum to carry on the work of investigation at our quarry now designated as the "Dinosaur National Monument" for the year of 1916; and for your further full information I am having a copy of the letter of the Secretary made, which I herewith transmit to you. You will observe that at the expiration of the year 1916 an application from us to continue our work will be considered,a nd so on from time to time until we may finally adjudge that it is no longer expedient for us to carry on our work in that spot. I wish especially to call your attention to the fact that at the end of the present year we will be required to exhibit a plat which would be reduced plan of the quarry, with such extensions as we may make during the present year, showing location of various bones contained therein. This work you will of course carry on as usual; and you also will keep a list of the specimens. I now write asking you to concentrate your efforts upon this quarry in the hope that you may be able to obtain some light, more particularly in refrence to the skulll of Apatasaurus
