Cretaceous fossil field in the world; will tell of our adventures and strenuous labor in the great gorge of the Red Deer river, 500 feet deep, and many miles in length; of the entire process of col leeting, learned by experience through so many years of ceaseless effort; also the work of prep aration in our laboratory. In 1917 it will be fifty years since I began collecting fossils, the rich results of the past few years are due to the splendid work done by my three sons of whom I am justly proud, and the assistance rendered.
