English: A school poster with a black and white photo in a white frame "1. The northern beach of Java, near Lasem" with bottom left: "Kleynenberg & Co., Haarlem". The photo was taken from a village on a bay, fringed by tropical vegetation. The village houses have gabled roofs. In the bay some deployed fishing nets. A number of professors and experts from that time have written explanatory texts for the school posters. The explanatory text accompanying this image is by J.F. Niermeyer: "There will be an opportunity later to speak about the character and the special beauty of the pristine Indian nature, about the mountain forest and the beach forest and the reed wilderness. First something will be said here, in connection with the first six plates of this series, about the landscape in which nature and culture both speak; in which man - not the European, but the Malay - has transformed the appearance of his environment according to his will and desire; never for deliberate embellishment; always only for habitation and for the recovery of everyday life bread; but with the result that thus, unsought, a harmonious whole was almost always created. The dwelling and the buildings, these are the works by which also elsewhere man has most modified the appearance of the earth; sometimes embellished, sometimes not but never as spoiled as industry and mining tend to be, which fortunately - and especially in India - operate on a smaller scale.However, much less than in our countries, the dwelling in the Indian landscape speaks, even in densely populated Java, yes there mainly. For the Javanese usually lives very simply, even too poor, and his huts are hidden under the fruit trees of his yards and behind the bamboo hedges that usually surround his villages. Our plates show exceptions to that rule exactly where most houses are indeed seen on Java: on the beach and high on the mountains. The first plate gives a view of a Javanese fishing village, the dessa Bonang, just east of Lasem, in the Rembang residence. The village lies close to the tide line, and although the coconut palms grow luxuriantly close to the sea beach, they do not come so close to the water as the houses of the fishermen, who can push their canoes through narrow, dug gullies to their front door. Pull. It is common on the calm beach of the Java Sea, where the surf remains far from the coast, that the villages and rice fields lie close to the sea; and the great post road also sometimes runs close to the bank, as here, where it is almost continuously accompanied by villages and chatterboxes. The beach forests of carrot trees and nipah, which in such great expanse accompany the low plains of Sumatra's east coast and of Borneo, occupy considerable length and breadth on Java's north coast only in the residences of Batavia and Cheribon. In the picture they are only seen protruding from the beach in a few small tongues, perhaps the remains of a former coastal forest. The slightly tinted area on the left in the background are the vast paddy fields of the almost horizontal plain, through which the small Kali Bogan, the river of Lasem, flows to the sea. The dark fringe on the horizon are the kampongs which form the chief town and which also border the K. Bogan to its north and south. In the coastal plains most of the villages are situated along the rivers, often in unbroken rows, not only because of the water consumption, but also because the higher riparian strips, thrown up by the floods, provide the driest places to live. The Bogan forms a small delta, with two mouths, the eastern one of which, however, does not always draw water, but is then fed by a few tributaries. It enters the sea in the center of the posterior plan of the plate. The western one is the main mouth, which has built a few sand dams into the sea (right). She used to be the middle one; a third estuary, still further to the west, is now dissolved in a series of pools. Thus we have here a small example of the usual phenomenon of the deltas: the ever-changing number of their mouths, as the Rhine delta also knew in its natural state. Clear sea water is blue in color and in the open tropical seas this blue is the rule. The Java Sea, however, has a clear green color, apparently due to a high silt content and the presence of a lot of clay and suspended organisms, the micro-plankton. The rivers of the islands of the Archipelago are very silty, and none of the inland seas has as many large rivers as their outlet in the Java Sea. In this sea there is also the peculiar phenomenon that only once a day a high tide and once a low tide can be observed. The cause of this seems to be that the tidal waves entering the Java Sea destroy each other's action, leaving no other phenomenon than the diurnal inequality caused by the declination of the moon.
