"Better take your coats and umbrellas with you to-day." We did not know then how many times during that day our thoughts would go back to the rainbow and the old superstition.
After breakfast we hitched up Old Sol, drove round by the Edwardses' to pick up Tom and Kate, and from there followed the lumber road into the great woods, to Otter Brook.

The "burnt lots" were perhaps a mile beyond the brook.
Addison and I picked blackberries for a while with the others; then, watching our chance, we stole away and made for the ledges, a mile or two to the northeast.
I had managed to bring a drill hammer along in my basket, wrapped up in my jacket; and Addison had brought a short drill in his pocket.

We found the ledge where Addison had made his discovery and had no great trouble in chipping off some specimens.

I may add here that the specimens later proved to contain silver--in small quantities.

I still have a few of them--mementos of youthful hopes that faded early in the light of greater knowledge.
We followed the ledges off to the northeast over several craggy hills.
At one place we found many exfoliating lumps of mica; we cleaved out sheets of it nearly a foot square, which Addison believed might prove valuable for stove doors.
While pottering with the mica, I accidentally broke into a kind of cavity, or pocket, in the ledge, partly filled with disintegrated rock; and on clearing out the loose stuff from this pocket we came upon a beautiful three-sided crystal about two inches long, like a prism, green in color, except at one end, where it shaded to pink.
It was a tourmaline crystal, similar to certain fine ones that have been found some miles to the eastward, at the now world-famous Mount Mica.
