Nothing can be more delightful than to study a science in this manner. It is pleasing to be schooled by the lips of those we love, and the wish to prove yourself deserving of the pains your master takes with you, will make you exert yourself to conquer any little difficulty you may meet with; while, on the other hand, your husband will be proud of the proficiency of his pupil, and a new occupation will be given to you, which will prevent your conversations becoming so monotonous as those of two persons who live together, and who see few strangers, would otherwise inevitably become. One of the great secrets for enabling a woman to render her husband happy, and, of course, to be happy herself, is partaking with him as much as possible in both his amusements and his studies. A woman should have as many subjects of interest as possible in common with her husband; and, in fact, she should have no objects of interest in the cares for which he cannot participate. It is true that in her domestic occupations she must be employed differently from him, as a man cannot interfere in the details of household arrangements; but a good wife will always have her husband's comfort in view, even when she is attending to her store-room or her kitchen; and she will be proud to show him the result of her labours in their due season. Men also have duties to attend to in which a woman cannot participate, such as those of a justice of the peace; and some manly sports, such as shooting and hunting. But these will often supply subjects for conversation, and afford that variety which gives life its greatest charm. It is, indeed, better that married people should have separate occupations during a part of the day; but they should never have separate interests, and they should always study to have as many subjects in common as possible. But I am forgetting that you have still two objects of natural history to be explained, which excited your attention during your walk. The first is the piece of stone that was picked up, and which, from the numerous particles it contains, was probably a piece of Granite, that is to say, if shining particles were mixed with others of a different nature; and it will be an amusement to you if you have any mineralogical specimens, to endeavour to find out what it is by comparing it with them; or, if you have not, to take it with you the first time you go to a town where there is a museum. The curious appearance you noticed in the clouds you will find, by consulting a book on meteorology, was of the kind called Cirrus, or, popularly, mare's tail, and that it is said to indicate the approach of windy weather.
