[[strikethrough]] ??[[/strikethrough]]

"We digested some of the pulps in ^[hot] water and found that [[strikethrough]] all [[/strikethrough]] ^[some of] the gold was soluble.  [[strikethrough]] ?  [[/strikethrough]]   By assaying the washed samples, we were able to arrive at an estimate of the value of the ore."

Salting mill samples where many tons of material are involved is more expensive and requires connivance of some of the employees either at the mine or at the mill, but is less easily detected than salting small samples.  However this is a very expensive process because of the quantity of gold involved and [[strikethrough]] is [[/strikethrough][] unless skillfully accomplished is easily proved if detected.  

In most gold ores, the fines contain much greater values than do the course parts of the ore.  Use may be made of this fact by a skillful and unscrupulous sampler, while coning and quartering the sample.  The honest procedure is to throuw the shovel  of [[strikethrough]] ? [[/strikethrough]] ore so that the material fall exactly on the center of the cone.  This assures a uniform distribution of the shovel full to the four quarters.  The salter if thoroughly familiar with the ore being handled is able to throw the fines so that they fall into the quarters to be taken next while the coarse parts go into the discarded quarters. 

Cornell.

Cornell was working on the dump sorting ore in a snowstorm.  In n Northern Arizona.  Because of some sculduggery, the assayer, superintendent, and metallurgist had all been fired from the mine.  the [[strikethrough]] ? [[/strikethrough]] new superintendent came out to the dump.

"Do you think you can handle the assay job, Cornell?"
