O'Brien!" "Yes, sir," answered another chainman, stepping forward.
"Take Thane with you, and carry Mr.Hazelton's transit to Grizzly Ledge.

Mr.Hazelton and I will be there presently." Two more chainmen started away.
Now, both of Tom's chainmen started forward, the rear one moving to the first metal stake that displayed the red marker.

Tom still remained at the transit, motioning to the men whenever they got the least out of a true straight line to the rodman.

It was not hard work for Reade at this point, but it required his closest attention.
After some time had passed the chainmen had "chained" the whole distance between Tom's stake and the rod resting on the next stake.
Now the rodman, after making a close measurement, signaled back.
Nine downward sweeps of his right arm signified nine chains; next the movements of his arm signaled the forty-four links of a tenth chain.

Then seven movements of the left hand across in front of the eyes, and Reade knew that stood for seven-tenths of a link.
