Manuscripts/Mixed Material [Oil Finders]
“When looking for other minerals, it was necessary to remove the oil capsule and substitute for it one which would respond to the particular mineral. For really accurate work, [?????] which could be used to determine [?] difference in the gravity of oil.
“It was [?] interesting and gratifying,” Dr. [?] continued, “to see the device start [??] approaching a producing well. Only the inventor could hold it, and it was necessary for him to be in motion to receive an indication, either walking or riding in an automobile. A few times, when we '[?]' rather suddenly upon a producer hidden in the timber, we observed violent rotations while a salt water capsule [?] being used, but who can say that there was no salt water below the oil? In every instance the device indicated oil after an oil capsule was [?].
“The device [???????]. It gave a rapid rotation on a tank containing ten feet of [?] crude which had originally been supposed to be full. The explanation was that the gravity of the oil [?] responsible. In order to test this explantation farther, the inventor was asked to try a tank of Sugarland oil. He did not know that the tank was empty at the time. The device rotated faster than ever, supposedly due to the gravity of the Sugarland oil which should have been in the tank!”
