Smell.
The sense of smell is one which greatly conduces to the preservation, the comfort, and the happiness of man. It is a continual aid to him in detecting polluted atmosphere or unhealthy food. The direct enjoyment it affords is probably less in amount than that derived from any of the other senses; yet, were we deprived of all the enjoyment gained through this source, we should probably find the privation much greater than we at first might imagine. When we walk forth among the beauties of nature, the fresh perfumes that send forth their incense are sources both of immediate and succeeding gratification. The beautiful images of nature which rise to the mind in our imaginative hours, would lose many of their obscure but charming associations were the fields stripped of the fragrance of their greens and the flowers of their sweet perfumes. Nature would appear to have lost that moving spirit of life which now ever rides upon the evening zephyrs and the summer breeze. As it is, as we walk abroad, all nature seems to send forth its welcome, while to its Maker's praise
"Each odorous leaf,
Each opening blossom, freely breathes abroad
Its gratitude, and thanks Him with its sweets."
Taste.
When a sapid body is applied to the organ of taste, two sensations are produced, one of touch and one of taste. We are conscious of the difference of these sensations when we apply a body to the tongue which has taste, and then immediately one which has not. It is probable, however, that the same set of nerves serve both purposes.
It is one of the numberless evidences of the benevolence of our Creator that the process which is necessary for the preservation of life, and which depends upon the voluntary activity of every human being, should be connected with a sense which affords such gratification that the duty is sought as a pleasure. Were mankind led to seek food merely in the exercise of reason for the purpose of preserving life, multitudes, through carelessness and forgetfulness, would be perpetually neglecting that regular supply without which the animal system would become deranged and enfeebled. By the present constitution of the body, the gratification of this sense is an object of desire, and thus we are continually reminded of our duty, and led to it as a source of enjoyment.
Nor is it the gratification of this sense which is the only source of enjoyment connected with it. The regular periods for repast bring around the social board those united to each other by the tenderest ties of kindred and affection. These become seasons of cheerful hilarity and relaxation, seasons of cessation from daily cares, seasons for the interchange of kind feelings and intellectual stores; and while the mere gratification of sense is one source of pleasure, to this is often added the "feast of reason and the flow of soul."
The effect on the best feelings in thus assembling to participate in common blessings is scarcely ever appreciated. Did every individual of our race retire to secrecy and solitude to satisfy the cravings of nature, how much would the sum of human happiness be diminished! But thus has our benevolent Creator contrived that one source of enjoyment should serve as an occasion for introducing many more.
