Brashear is practically the one telescope lens-maker of America since Alvan Clark resigned. There is no competition in this line—the difficulties are too appalling for the average man. The slightest accident or an unseen flaw, and the work of months or years goes into the dustbin of time, and all must be gone over again.
So when we think of this brother and sister sailing away upon an unknown ocean—working day after day, night after night, week after week, and month after month, discarding scores of specula which they had worked upon many weary hours in order to get the glass that would serve their purpose—we must remove our hats in reverence.
God sends great men in groups. From Seventeen Hundred Forty for the next thirty-five years the intellectual sky seemed full of shooting-stars. Watt had watched to a purpose his mother's teakettle; Boston Harbor was transformed into another kind of Hyson dish; Franklin had been busy with kite and key; Gibbon was writing his "Decline and Fall"; Fate was pitting the Pitts against Fox; Hume was challenging worshipers of a Fetish and supplying arguments still bright with use; Voltaire and Rousseau were preparing the way for Madame Guillotine; Horace Walpole was printing marvelous books at his private press at Strawberry Hill; Sheridan was writing autobiographical comedies; David Garrick was mimicking his way to immortality; Gainsborough was working the apotheosis of a hat; Reynolds, Lawrence, Romney, and West, the American, were forming an English School of Art; George Washington and George the Third were linking their names preparatory to sending them down the ages; Boswell was penning undying gossip; Blackstone was writing his "Commentaries" for legal lights unborn; Thomas Paine was getting his name on the blacklist of orthodoxy; Burke, the Irishman, was polishing his brogue so that he might be known as England's greatest orator; the little Corsican was dreaming dreams of conquest; Wellesley was having presentiments of coming difficulties; Goldsmith was giving dinners with bailiffs for servants; Hastings was defending a suit where the chief participants were to die before a verdict was rendered; Captain Cook was giving to this world new lands; while William Herschel and his sister were showing the world still other worlds, till then unknown.
hen the brother and sister had followed the subject of astronomy as far as Ferguson had followed it, and knew all that he knew, they thought they surely would be content.
Progress depends upon continually being dissatisfied. Now Ferguson aggravated them by his limitations.
In their music they amused, animated and inspired the fashionable idlers.
William gave lessons to his private pupils, led his orchestra, played the organ and harpsichord, and managed to make ends meet, and would have gotten reasonably rich had he not invested his spare cash in lenses, brass tubes, eyepieces, specula and other such trifles, and stood most of the night out on the lawn peering at the sky.
He had been studying stars for seven years before the Bath that he amused awoke to the fact that there was a genius among them. And this genius was not the idolized Beau Nash whose statue adorned the Pump-Room! No, it was the man whose back they saw at the concerts.
During all these years Herschel had worked alone, and he had scarcely ever mentioned the subject of astronomy with any one save his sister.
