These piles are all controlled by the patenteesor those licensed by them, who take contracts for doing the workthemselves. Mr. Gillette gives costs for the Simplex, 10 centsper lineal foot, which should also be about the cost of thepedestal pile.

The sections are fitted together as thedriving proceeds by means of an interior sleeve; the pile may bedriven with a cast point, or if without a point the dirt or sand. Fig. 206.
