    He had, therefore, full opportunities of seeing the country and its life from various points of view. He has utilized his observations in an entertaining book. It is not — and does not pretend lo be — a scientific work, or technical in any sense. It gives, however, an excellent idea of conditions and ways of living in the Klondike at all seasons, and of the hardships which the pioneers had to undergo. Nothing but gold — the prospect of wealth — could induce men to live in such a climate, and to combat the many difficulties which it entails. Mr. Lynch, a Californian of means and position, arrived at Dawson in the summer of 1898. As the first discoveries of gold in the Klondike valley were made in August of 1896, Mr. Lynch found a mining town not two years old, unpaved and insanitary, crowded with adventurers of every nation, in fact still a typical “ tough" mining-camp, except that lawlessness and crime were sternly repressed by the vigilant Mounted Police. He spent the following winter in the town, making expeditions to the gold-bearing creeks, examining mines and studying the methods of working them. Early in the spring of 1899 he bought a claim which he believed would repay him and set himself at once to develop it thoroughly. During his stay he had seen Dawson transformed into a paved, sewaged, well built, well lighted city, and the streets, no longer thronged with rough-mannered miners and adventurers, had become the promenade of well dressed business men and ladies (real ladies !) intent on shopping. As one of the earliest of the new species of Klondike miner, he is able to give an account of the transition that took place, largely owing to the enterprise of men of his own stamp, and the book is an interesting addition to Klondike literature. Mr. Lynch's narrative is plainly written, in a way which leads one to believe in its substantial truth. It reads well, and brings out many points which will interest the miner, as well as the casual reader. He had confidence in the future of the country, and believed that it would hold a large population for many years, in spite of the drawbacks of climate.

    At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges--Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates.The "glass universe" of half a million plates that Harvard amassed over the ensuing decades--through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography--enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard--and Harvard's first female department chair.
