_The Great Yield of the Quarry._ Our explorations in the quarry began
in the spring of 1898, and have continued ever since during favorable
weather. The total area explored at the close of the sixth year was
seven thousand two hundred and fifty square feet. Not one of the
twelve-foot squares into which the quarry was plotted lacked its
covering of bones, and in some cases the bones were two or three deep.
Each year we have expected to come to the end of this great deposit,
but it still yields a large return, although we have reason to believe
that we have exhausted the richest portions.
We have taken up four hundred and eighty-three parts of animals, some
of which may belong to the same individuals. These were packed in two
hundred and seventy-five boxes, representing a gross weight of nearly
one hundred thousand pounds. Reckoning from the number of thigh-bones,
we reach, as a rough estimate of the total, seventy-three animals of
the following kinds: giant herbivorous dinosaurs, 44; plated
herbivorous dinosaurs, or stegosaurs, 3; iguanodonts or smaller
herbivorous dinosaurs, 4; large carnivorous dinosaurs, 6; small
carnivorous dinosaurs, 3; crocodiles, 4; turtles, 5. But this
represents only a part of the whole deposit, which we know to be of
twice the extent already explored, and these figures do not include
the bones which were partly washed out and used in the construction
of the Bone-Cabin. The grand total would probably include parts of
over one hundred giant dinosaurs.
