On the other hand, the eagle, on account of its structure and large size, is a prisoner indeed, and must languish with all its splendid faculties and importunate impulses unexercised. You may gorge it with gobbets of flesh until its stomach cries, "Enough"; but what of all the other organs fed by the stomach, and their correlated faculties? Every bone and muscle and fibre, every feather and scale, is instinct with an energy which you cannot satisfy, and which is like an eternal hunger. Chain it by the feet, or place it in a cage fifty feet wide--in either case it is just as miserable. The illimitable fields of thin cold air, where it outrides the winds and soars exulting beyond the clouds, alone can give free space for the display of its powers and scope to its boundless energies. Nor to the power of flight alone, but also to a vision formed for sweeping wide horizons, and perceiving objects at distances which to short-sighted man seem almost miraculous. Doubtless, eagles, like men, possess some adaptiveness, else they would perish in their enforced inactivity, swallowing without hunger and assimilating without pleasure the cold coarse flesh we give them. A human being can exist, and even be tolerably cheerful, with limbs paralyzed and hearing gone; and that, to my mind, would be a parallel case to that of the eagle deprived of its liberty and of the power to exercise its flight, vision, and predatory instincts. As I sit writing these thoughts, with a cage containing four canaries on the table before me, I cannot help congratulating these little prisoners on their comparatively happy fate in having been born, or hatched, finches and not eagles. And yet albeit I am not responsible for the restraint which has been put upon them, and am not their owner, being only a visitor in the house, I am troubled with some uncomfortable feelings concerning their condition--feelings which have an admixture of something like a sense of shame or guilt, as if an injustice had been done, and I had stood by consenting. I did not do it, but we did it. I remember Matthew Arnold's feeling lines on his dead canary, "Poor Matthias," and quote: Yet, poor bird, thy tiny corse Moves me, somehow, to remorse; Something haunts my conscience, brings Sad, compunctious visitings. Other favourites, dwelling here, Open lived with us, and near; Well we knew when they were glad Plain we saw if they were sad; Sympathy could feel and show Both in weal of theirs and woe. Birds, companions more unknown, Live beside us, but alone; Finding not, do all they can, Passage from their souls to man. Kindness we bestow and praise, Laud their plumage, greet their lays; Still, beneath their feathered breast Stirs a history unexpressed. Wishes there, and feeling strong, Incommunicably throng; What they want we cannot guess.
