Σελίδα 352 - When these differences occur the surveyor will in all cases establish the missing corner by proportionate measurements on lines conforming to the original field notes and by the method followed in the original survey. From this rule there can be no departure, since it is the basis upon which the whole operation depends for accuracy and truth.
Σελίδα 597 - There are many more shining qualities in the mind of man, but there is none so useful as discretion ; it is this indeed which gives a value to all the rest, which sets them at work in their proper times and places, and turns them to the advantage of the person who is possessed of them.
