Thoreau's Journal: 07-Jun-1851
My practicalness is not to be trusted to the last. To be sure, I go upon my legs for the most part, being hard-pushed and dogged by a superficial common sense which is bound to near objects by beaten paths, I am off the handle, as the phrase is—I begin to be transcendental and show where my heart is. I am like those guinea-fowl which Charles Darwin saw at the cape de Verd Islands. He says, “They avoided us like partridges on a rainy day in September, running with their heads cocked up; and if pursed, they readily took to the wing.” Keep your distance, do not infringe on the interval between us, and I will pick up lime and lay real terrestrial eggs for you, and let you know by cackling when I have done it.
