Thoreau writes in his journal:
I have been to-night with Anthony Wright to look through Perez Blood’s telescope a second time. A dozen of Blood’s neighbors were swept along in the stream of our curiosity. One who lived half a mile this side said that Blood had been down that way within a day or two with his terrestrial, or day, glass, looking into the eastern horizon [at] the hills of Billerica, Burlington, and Woburn. I was amused to see what sort of respect this man with a telescope had obtained from his neighbors, something akin to that which savages award to civilized men though in this case the interval between the parties was very slight. Mr. Blood, with his skull-cap on, his short figure, his north European figure, made me think of Tycho Brahe. He did not invite us into his house this cool evening,—men nor women,—nor did he ever before to my knowledge. I am still contended to see the stars with my naked eye. Mr. Wright asked him what his instrument cost. He answered, “Well, that is something I don’t like to tell.” (Stuttering or hesitating in his speech a little as usual.) “It is a very proper question, however.” “Yes,” said I, “and you have given a very proper answer.” Returning, my companion, Wright, the sexton, told me how dusty he found it digging a grave that afternoon,—for one who had been a pupil of mine. For two feet, he said, notwithstanding the rain, he found the soil as dry as ashes.
