John Bell Hatcher— Schucbert. 133 
months he collected in the older Mesozoic deposits around 
Washington, D. C, Richmond, Va., and in North Carolina. 
The age of these beds had heretofore not been satisfactorily 
determined, but here as elsewhere Hatcher was successful 
in securing near Washington considerable dinosaur mate- 
rial, which thus enabled Marsh to prove the presence in this 
region of the Upper Jurassic formation. In 1S88 he was 
again at Long Pine and Chadron, but also investigated new 
regions — the Judith river of Montana and Hermosa, South 
Dakota. In the spring of 1889 he discovered the first 
T7-iceratops, near Lusk, Wyoming, and continued to ex- 
hume these large and remarkable dinosaurs until 1892. 
During this time he took up not less than 50 individuals of 
CeratopSia, 33 of which had more or less perfect skulls ; also 
parts of ten or more and two remarkably complete skele- 
tons of Claosaurus now mounted in high relief — one at the 
U. S. National Museum, the other at Yale. During this 
period, also, he collected in a new and novel way many 
Laramie mammals from ant hills. To secure these small 
remains, one man would hold a bag while another would 
throw into it rapidly several shovelfulls of the '"mammal 
sand," leaving the bag until the next day, when all the ants 
would be found to have crawled out of the dirt. 
When with Marsh at New Haven, Hatcher's time was 
devoted to the preparation and study of the fossils he had 
collected, and to familiarizing himself with them as an aid 
to further field work. From 1884 to 1892 he sent in nearly 
900 boxes of vertebrate material. As a rule, these boxes 
were of large size, and one exceeded three tons in weight. 
This huge box (about 10 feet long, 5 feet wide and 6 feet 
deep) contained the largest known skull of Triceratops, 
had to be lifted out of a ravine fifty feet deep, and hauled to 
the railroad over a trackless country and through streams 
for more than forty miles. It is no exaggeration to state 
that during the 20 years of Hatcher's paleontological activ- 
ity, he with the assistance of a few field helpers sent to the 
U. S. National Museum, and to Yale, Princeton, and Car- 
negie museums, not less than 1500 boxes of fossils. This 
is a record that will stand unequaled. a work that Hatcher 
loved, resulting in material part of which he hoped it would
