Dr. Mary Walker never returned to St. Paul, and her exact whereabouts are not known, though every effort was made to find her. Fragments of flypaper and brindle hair were found as far west as the Yellowstone National Park, and as far north as the British line, but the doctor herself was not found. My own theory is, that if she turned her bow to the west so as to catch the strong easterly gale on her quarter, with the sail she had set and her tail pointing directly toward the zenith, the chances for Dr. Mary Walker's immediate return are extremely slim. [Illustration] The Heyday of Life. There will always be a slight difference in the opinions of the young and the mature, relative to the general plan on which the solar system should be operated, no doubt. There are also points of disagreement in other matters, and it looks as though there always would be. To the young the future has a more roseate hue. The roseate hue comes high, but we have to use it in this place. To the young there spreads out across the horizon a glorious range of possibilities. After the youth has endorsed for an intimate friend a few times, and purchased the paper at the bank himself later on, the horizon won't seem to horizon so tumultuously as it did aforetime. I remember at one time of purchasing such a piece of accommodation paper at a bank, and I still have it. I didn't need it any more than a cat needs eleven tails at one and the same time. Still the bank made it an object for me, and I secured it. Such things as these harshly knock the flush and bloom off the cheek of youth, and prompt us to turn the strawberry box bottom side up before we purchase it. Youth is gay and hopeful, age is covered with experience and scars where the skin has been knocked off and had to grow on again. To the young a dollar looks large and strong, but to the middle-aged and the old it is weak and inefficient. When we are in the heyday and fizz of existence, we believe everything; but after awhile we murmur: “What's that you are givin' us,” or words of like character. Age brings caution and a lot of shop-worn experience, purchased at the highest market price. Time brings vain regrets and wisdom teeth that can be left in a glass of water over night. Still we should not repine. If people would repine less and try harder to get up an appetite by persweating in someone's vineyard at so much per diem, it would be better. The American people of late years seem to have a deeper and deadlier repugnance for mannish industry, and there seems to be a growing opinion that our crops are more abundant when saturated with foreign perspiration. European sweat, if I may be allowed to use such a low term, is very good in its place, but the native-born Duke of Dakota, or the Earl of York State should remember that the matter of perspiration and posterity should not be left solely to the foreigner.
