It prefers the waters of temperate or cold areas and can be found only in the Northern Hemisphere.
During the breeding season in early summer large shoals of sturgeon swim into rivers or towards the shores of freshwater lakes. In Europe sturgeon occur from Scandinavia to the Mediterranean and in particular several species are found in the Caspian Sea and the Black Sea.
Another new Malaysia’s book of record. 732 Santa Claus & Santarina joined Christmas treasure hunt at Spritzer Eco Park. Well done to the organiser who helped to promote Taiping, our own heritage city. 🎄🎄
So many mishaps have befallen the inexperienced mountaineers whose desire to pick an edelweiss has driven them up to the top, that many imagine that this flower only grows on impossible mountain peaks.
In actual fact, the edelweiss grows wherever the soil is calcareous at an altitude of more than 1,500 metres, and it can also be found at a lower altitude in the valleys. In certain areas at more than 2,000 metres which are rarely visited by man, it is possible to find these flowers growing in open spaces among the grass.
In easily reached places, however this flower has been almost completely destroyed by excessive gathering. This is why edelweiss now only inhabits the almost inaccessible and dangerous parts of the mountain.
This plant can be cultivated in rock gardens and given ideal conditions it will produce a very large corolla. It also grows in open country but here its petals tend to lose their hairy protection and assume a greenish colour.
Since ancient times man has exploited the forces of nature in an effort to obtain from them the greatest possible aid from his work. One of these forces is the wind; caught in the sails of a boat or used for turning the sails of a windmill, it is the workman’s oldest tool and a help to human labours.
Today the country famous throughout the world for its windmills is Holland, a flat windy country whose people have the reputation of being among the most industrious and enterprising in the world.
For many centuries the characteristic towers of the windmills have made the countryside of the Low Countries quite unmistakable. These windmills have varying forms; rounded and slightly conical, prismatic, pretty, decorative and unadorned. All of them however are positioned so as to receive the greatest force of the wind; the sails, which a breath of air will put in motion, rise over them all.
In Holland, windmills are used more for lifting water than for milling grain. In order to drain the land, they are used to pass water from one canal to another and it is in this way that a country which has always been at war with water manages to maintain hydraulic balance.
The celebrated grottoes of Postojna are situated in a karst field in western Slovenia. Tortuous galleries caves, magnificent rooms richly decorated with stalagmites and stalagtites stretch for nearly thirty kilometres. The river Pivka flows in one of the most fantastic subterranean beds in the world.
The grottoes of Postojna have been famous since 1213 engraved in one wall you can read the signatures of people who visited the grottoes as long ago as 1250. But the caves were unknown in modern times until 1818.
Today, tourists can visit the caves in a small electrified railway. Among the most celebrated are the Concert Hall, the Ballroom and the Paradise Grotto.
