"And the best place to get a grizzly bear rug for a Boy Scout club room in Chicago," Sandy laughed, "is in a range of foot hills built mostly of limestone. You see," the lad continued, "water washes out limestone and leaves caves and holes which the bears occupy. Sometimes these caves and holes furnish accommodation for a whole family of baby bears, I have heard, so we may be able to take a pet cub back to Chicago with us. That would be pretty poor, I guess!"
