approximation to the limits of Middle Germany may be obtained by regarding it as a triangle, of which one angle lies in Silesia, another in Aix-la-Chapelle, and a third at Lake Constance. This triple division corresponds with the broad distinctions of climate. In the northern plains the atmosphere is damp and heavy; in the southern mountain region it is dry and rare, and there are abrupt changes of temperature, sharp contrasts between the seasons, and devastating storms; but in both these zones men are hardened by conflict with the roughness of the climate. In Middle Germany, on the contrary, there is little of this struggle; the seasons are more equable, and the mild, soft air of the valleys tends to make the inhabitants luxurious and sensitive to hardships. It is only in exceptional mountain districts that one is here reminded of the rough, bracing air on the heights of Southern Germany. It is a curious fact that, as the air becomes gradually lighter and rarer from the North German coast toward Upper Germany, the average of suicides regularly decreases. Mecklenburg has the highest number, then Prussia, while the fewest suicides occur in Bavaria and Austria. Both the northern and southern regions have still a large extent of waste lands, downs, morasses, and heaths; and to these are added, in the south, abundance of snow-fields and naked rock; while in Middle Germany culture has almost over-spread the face of the land, and there are no large tracts of waste. There is the same proportion in the distribution of forests. Again, in the north we see a monotonous continuity of wheat-fields, potato-grounds, meadow-lands, and vast heaths, and there is the same uniformity of culture over large surfaces in the southern table-lands and the Alpine pastures. In Middle Germany, on the contrary, there is a perpetual variety of crops within a short space; the diversity of land surface and the corresponding variety in the species of plants are an invitation to the splitting up of estates, and this again encourages to the utmost the motley character of the cultivation.
