Pier.

Patent for a new and improved pier. This design "is to provide a new and improved pier which is simple and durable in construction, possesses great stability and strength, is readily sunk in the water and fastened in place, arranged to be built up to any desired height, and designed so as to cut the water in order to reduce the power of the current to a minimum. The invention consists of a series of rods formed at their lower ends with augers and adapted to pass through ears of an exterior shell forming the wall or casing of the pier" (lines 9-20).
