The fore chainman sticks the stake where directed and drops a grade stake by it. He then pulls ahead another length of the chain and is again put into line. The rear chainman drives the stakes and marks them with a large lead-pencil in order, calling the first stake o and the next i, etc., for all full stations from outlet to the upper end of the drain. Where curves are made, intermediate stakes should be set in such a way that they can be followed and used in digging the ditch, and should be marked so as to indicate the number of feet from the outlet up to each.
