Decay can also be prevented by submergence and burying, if by so doing logs are kept from fungal attacks.
Clearly the island of Jersey underwent in those days some sort of submergence.
It is probable, too, that the submergence destroyed a good many plants and the insects dependent on them.
The depth of the submergence in this case was only a few feet, but great depths may be reached with relative safety.
The memory of extinct nations is perpetuated by the clay records which have survived their submergence in the tide of time.
Neither tree nor bush grew upon it; their absence indicating that it was subject to annual submergence in the season of rain.
It is to the sediments deposited during the earlier part of this submergence that the name Potsdam is given.
These beds are charged with the relics of a boreal and arctic fauna, and indicate a submergence of rather more than 100 feet.
Indeed, as in North America, the submergence has decreased on the average since the Paleozoic era.
But it cannot pass until my wife comes up out of the submergence.
