The mineral waters of Hungary By Dr. Nicholas Frank The author gives us quite new results of researches about such recently exploited mineral waters which after the opening work of the geologist, have been thoroughly examined alsó by the chemical experts and the balneologists. Besides he proposes the regular chemical control of the mineral waters, the regular examination of their healing effect and the control of their wattersoupply. Only so we can assure the complete opening of our mineral waters and their lucrative exploitation in the interest of our people's economy. The surface of Hungary'a catchment area dr. Alexander Láng The paper briefly summarizes the developmet of Hungary's present surface, mainly on the basis of the newer works done in the field of geomorphology by Béla Bulla, Ladislas KádSr, Andífw Kéz and the author and on the ground of the results of the freshest geological survey of the Hungárián Plain and Transdanubia accomplisbed by Josepli Siimeghy and his collaborators ; the latter work has been executed under the auspices and in the framework of the State Geological Institution. The paper practieally discusses the greater or lesser geomorphological land units of Hungary ratber from a bird's eye view and quite abridged. The author wishes to present, at the same time, the modern geomorphological view to those active in praetical researeh, but chiefly to hydrologists. Of the most important results in this study we may lay particular stress upon the statements made on the juvenile faneharacter of the ridge between Danube and Tisza and of the Nyirség (sandy landscape unit in NE Hungary) (on the hasis of nvestigatons made by B_lla and Kádár respectivelv), the young settling character of the Danube and and TÍ9za valLys in the Hungárián Plain and of the past swampy and marshy little basins (researeh carried out by Bulla, Siimeghy and the author) and finally the peneplain and afterwards the lifting in reeent times of the hilly and mountanoui regions (investigations of the author). The Pálvölgy cavern . Slephen Venkovits The author deals with the development-history of the Pálvölgy cavern. He summarized in it the results of his geological observations and chemical investigations gathered in a long series of years. In the introduction he deals, in generál, with the karst — phenomena devcloping alsó in our days, espeeially from the point of view of the balance between lime and earbonie aeid. He alsó embraces the subject of the origin of cavity systems and specially globulous pattéra, that are in no connection with the karst activity of today He then turns to the classification of the various kinds of caverns. Dealing with the Pálvölgy cavern, he first guides us along the main shafts and acquaints us in detail with their origins. He supplies us important data on the variation of the carbonic aeid eontent of the cave-air. He minuticusly pojnts out the gallery parts widened either by the action of dissolution or, by tectonic influences. The author renders account alsó of the originál circumstances of the origin of mineral associations of the cave. The cave is a network of fissures, evolved along tectonic plane9, enlarged by thermal waters, decorated by aceretions of the subsiding waters. The abyssical dissolutive action has repeatedly acted in it. The author alsó mentions the of development cf the Pálvölgy cavern. In his opinion, the first fissures förmed, at 239 the end of the Eocene period, with the Pyrenéen movements ; the corrosive action of water had already begun at that time, The shifting of nummulinic lime, which is full of galleries upon the triadic hornstone lime, occrurred after the Pannonian period. The author forwards our knowledge extensively about the origin of the much frequented Pálvölgy cavern. The examination of the watergiving strata of bored wells By Joseph Gerhardt The socialist reconstruction of the country projected the far reaching development of the backward supply of drinking water. It refers espeeially to our industrial areas and to our towns. Examining the possibilities of opening water in our country, this is mostly possible by bored Wells. The most sensible part of the Wells is the filter-machine, througli which the water comes from the stratum into the well. Of course, we are unable to altér the natural situation of the stratum and so we cannot increase the produceable quantity of water from a well but by the proper formation of the filter-pipe. The author accomplished the examinations ot the watergiving stratum of about 100 of the Wells built during 1951 and he tried to establish somé connectiens among the structure of the watergiving stratum, the diameter of the well and the formation of the filter-pipe. He appreciated the results after the caleulations of F. S. Bojarincev, published in Moscow, 1949, in his book Planing and Execution of Bored Wells of great Achievement The calculation of the water production of the Well is made with the help oftheDupuit formula but passing over from the theoretical well to the praetical one, he talces into consideration the factor of going over. The latter contains all the changes which take place in the originál condition of the watergeving stratum after the the filter-pipe was built in. These are : the watertaking capacity of the filter-pipe, the watergiving capacity of the stratum, the stratum-water förmed by pumping and the effect of graveling, which increases the watcrproduction. According to this system the author accon püshed caleulations on the basis of different possibilities of filtration and he coneluded that the filtration by sieve cloth, generally used in this country doesn't enable us to get water of greater quantity from our watergiving strata, which consist as a rule of sím 11 grits. Instead of the above mentioned inaterial he proposes to apply gravelfilters of wire, by whieh after the caleulations of the author about 400% more water can be produced from the watergiving strata. Wirtschaftliche Zusammenarbeit der Thermischen und Waíserkraftwerke von Ladislaus Török Der Artikel verhandelt die in der Sowjetunion gebráuchlichen Methoden, mit welchen die Selbstkosten der erzeugten Energie in einem gemischt ausgebauten Energiesystem (welches aus Thermische und Was9erkraftwerke besteht) auf das minimalste reduziert werden können. Diese wirtschaftliche Energieerzeugung erreichen wir durch die Verteilung der Belastung im bestimmten Masse zwischen den einzelnen Thermischen- und Wasserkraftanlagen. Der Artikel gibt die theoretischen Regei der Bclastungsverteilung bekannt und befasst sich detailliert mit den in der Sowjetunion angewandten praktischen Methoden, welche zur Lösung des Problems dienen, mit besonderer Rücksicht auf diejenigen Lösungen, welche bei den heimatlichen Verhaltnissen (Kraftanlagen mit kleinem Gefalle, tágliche oder wöchentliche Speicherung) mit Erfolg angewendet werden können. Anderungen des natiirliehen Ertrages der Fischteiche von Dr. techn. Paul Erős In unseren teichwirtschaftlichen Betriebsprojekten betrachten wir den natiirliehen Ertrag der Fischteiche als den die Produktionskraff des Tciches charakterisierenden Beiwert für bestandig. Wir wissen jedoch, dass der Wert des natiirliehen Ertrages eigentlich niclit bestandig, sondern mehr oder weniger wechselnd ist. Zwecks Erlauterung dieser Frage, bilden die aus den praktischen Produktionsergebnissen der Buzsák-er Teichwirtschaft durch das eigene System des Verfassers berechneten Werte des natiirliehen Ertrages den Gegenstand
