He can route the sun Arcturus, He can map Orion's bands; He can lure us and assure us, For we know he understands. Scarcely anything to speak of 'Scapes his trusty spectroscope; But a hairy, scary streak of Gas defies his deepest dope. A comet always gets him, Always frets him and upsets him; For he can't make head or tail of it at all.

A Penny Whistle, The Astronomer (p. 23), Alfred A. Knopf. 1921
