"Of no direct use that I know of, William; but if it has no other use than to induce you to reflect a little, it has not been made in vain. All created things are not applicable to the wants or the enjoyment of man; but their examination will always tend to his improvement. When you analyse this little creature in its domicile, and see how wonderfully it is provided with all means necessary for its existence,-- when you compare it with the thousand varieties upon the beach, in all of which you will perceive the same Master-hand visible, the same attention in providing for their wants, the same minute and endless beauty of colour and of form,--you cannot but acknowledge the vastness and the magnificence of the Maker. In the same manner the flowers and shrubs, which embellish, as they cover the earth, are not all so much for use, as they are for ornament. What human ingenuity can approach to the perfection of the meanest effort of the Almighty hand? Has it not been pointed out in the Scriptures, `Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon, in all his glory, was not arrayed like one of these.' Never debate in your mind, Willy, of what use are these things which God has made--for of what _use_, then, is man, the most endowed and the most perverse of all creation, except to show the goodness and the forbearance of the Almighty! You may, hereafter, be inclined to debate why noxious reptiles and ferocious beasts, that not only are useless to man, but a source of dread and of danger, have been created. They have their inheritance upon earth, as well as man, and combine with the rest of animated nature to show the power, and the wisdom, and the endless variety of the Creator. It is true that all animals were made for our use; but recollect, that when man fell from his perfect state, it was declared, `In the sweat of thy brow thou shalt eat bread.' Are trackless forests and yet unexplored regions to remain without living creatures to enjoy them, until they shall be required by man? And is man, in his fallen state, to possess all the earth and its advantages, without labour,--without fulfilling his destiny? No. Ferocious and noxious animals disappear only before cultivation. It is part of the labour to which he has been sentenced, that he should rend them out as the `thistle and the thorn;' or drive them to those regions, which are not yet required by him, and of which they may continue to have possession undisturbed." Such was the language of Macallan to our hero, whose thirst for knowledge constantly made fresh demands upon the surgeon's fund of information; and, pedantic as his language may appear, it contained important truths, which were treasured up by the retentive memory of his pupil. ------------------------------------------------------------------------
