We quote the following suggestion from the observation of a traveler: "It appears to me that the power and riches of these extraordinary districts remain yet to be fully developed. They exhibit an immense number of mighty steam-engines, furnished by nature at no cost, and applicable to the production of an infinite variety of objects. In the progress of time this vast machinery of heat and force will probably become the moving central point of extensive manufacturing establishments. The steam which has been so ingeniously applied to the concentration and evaporation of the boracic acid, will probably hereafter, instead of wasting itself in the air, be employed to move huge engines, which will be directed to the infinite variety of production which engages the attention of the industrious artisans; and thus in course of time there can be little doubt that these lagoons, which were fled from as objects of danger and terror by uninstructed man, will gather round them a large, intelligent population, and become sources of prosperity to innumerable individuals through countless generations." Whoever has traveled through Tuscany, will every where have observed that the peasants live in better houses than they do any where else in Europe. Some one has said that nearly all their dwellings have been built within the last eighty years, an observation which in itself shows the substantial nature of their tenements, for where else will a peasant's house last so long? In the secluded mountain valleys, where agriculture supplies the only employment of the industrious classes, you sometimes meet with very ancient cottages, built quite in the style of the middle ages, with an abundance of projection and recesses, all calculated to produce picturesqueness of effect. The modern houses, more particularly in the district of the lagoons, are constructed more with reference to comfort than show, the object being to secure as much room and air as possible. In most places a garden is attached to every dwelling; and where trees will grow, a large linden or chestnut stretches its large boughs lovingly about the corner, and sometimes over the roof, of the dwelling. Under this the peasant and his family sit to enjoy themselves on summer evenings. Not to be entirely idle, however, the father is usually engaged in weaving baskets, while the children amuse themselves with cleaning and preparing the twigs; the mother, often with a baby in her lap, applies herself to the reparation of the family wardrobe; and the whole group, especially when lighted up by the slanting rays of the setting sun, presents to the eye a picture not to be equaled by Dutch or Flemish school.
