Saturday November 10th was the last time that the entire WI class spent on the Isle Royale Rock Piles. This does not mean, however, that operations will cease altogether, for as long as the weather permits the class will conduct individual operations in search of the rarer crystals.
Hundreds of specimens have been collected by every one in the class. One man even used his Ford Runabout to haul rocks home. He evidently intends to surpass all previous records in the number and variety of crystals handed in.
Despite the energetic efforts of the class the piles of rock remaining seem as large as ever. Mr. W.A. Seaman thinks that he can continue separations there for many reasons to come. The domeykite outcrop however is being used up rapidly. If no new deposits are discovered, underground mining will be necessary in a few decades, and it is feared that the Mining Department will then want to pass on some of the methods used.
The work this year was confined mostly to the Old Huron and Number One rock piles, these considered the most promising places. Evidently the previous classes were rather careless, for large finds of some of the rare crystals are being reported by many of the fellows.
