The rôle of discoverer is pleasing, nearly always, and more especially in its reactions is it pleasing. The actual performance of discovery may be fraught with hardships and with inconveniences and even with perils; as witness Christopher Columbus making his first voyage over this way in a walloping window-blind of a tub of a ship and his last one back with chains at his wrists and ankles; as witness Hendrick Hudson; as witness Dr. Harvey's unfortunate position in the eye of constituted authority after he had discovered the circulation of the blood; as witness the lamentable consequences to whoever it was who, probably by the process of eating a mess of miscellaneous wild fungoids, disclosed to a bereaved family and a benefited world the important fact that certain mushrooms were nourishing and certain toadstools were fatal.
