Thoreau writes in his journal on 29 June:
Yesterday the air was filled with a thick fog-like haze, so that the sun did not once shine with ardor, but everything was so tempered under this thin veil that it was a luxury merely to be outdoors,—you were less out for it . . . I saw some hills on this side the river, looking from Conantum, on which, the grass being of a yellow tinge, though the sun did not shine out on them, they had the appearance of being shone upon peculiarly . . . Riding to survey a wood-lot yesterday, I observed that a dog accompanied the wagon. Having tied the horse at the last house and entered the woods, I saw no more of the dog while there; but when riding back to the village, I saw the dog again running by the wagon, and in answer to my inquiry was told that the horse and wagon were hired and the dog always accompanied the horse. I queried whether it might happen that a dog would accompany the wagon if a strange horse were put into it; whether he would attach to an inanimate object. Methinks the driver, though a stranger, as it were added intellect to the mere animality of the horse, and the dog, not making very nice distinctions, yielded respect to the horse and equipage as if it were human. If the horse were to trot off alone without a wagon or driver, I think it doubtful if the dog would follow; if with the wagon, then the chances of his following would be increased; but if with a driver, though a stranger, I have found by experience that he would follow.
