It is impossible to be in this high spinal country without giving thought to the first men who crossed it, the French explorers, the Lewis and Clark men. We fly it in five hours, drive it in a week, dawdle it as I was doing in a month or six weeks. But Lewis and Clark and their party started in St. Louis in 1804 and returned in 1806. And if we get to thinking we are men, we might remember that in the two and a half years of pushing through wild and unknown country to the Pacific Ocean and then back, only one man died and only one deserted. And we get sick if the milk delivery is late and nearly die of heart failure if there is an elevator strike. What must these men have thought as a really new world unrolled --or was the progress so slow that the impact was lost? I can't believe they were unimpressed. Certainly their report to the government is an excited and an exciting document. They were not confused. They knew what they had found.
