    Recently, underground gas storage has attracted special attention of town gas and all other energy industries.This method of gas storage in America is rather old and in Germany and France its actual operations have got under way in these several years.As its possibility can be expected in our country where various conditions are very alike to the above two countries, Tokyo Gas Co.has started investigations in all lines.While there are several methods of underground gas storage, we tried, in this paper, to describe principles, investigations, construction and operation concerning a method which appears to be most feasible in our country.

    Instrumental analyses have made remarkable progress recently.They have been possible to analyse the complicated components and to soluble the reaction mechanism in processes.They have also been used in control tests because the time required is very short.
    In this paper, recent advances and applications of various kinds of instrumental analyses in petroleum industry gas chromatography, mass spectrography and spectrometry (infrared absorption, raman, ultraviolet absorption speetrometry and nuclear magnetic resonance) are reviewed.

    Recently, hydraulic transport of coal in pipes became remarkable as a new transport method at coal mines, because this method has many merits in comparison with ordinary trausport methods applieds at coal mines.Then, many studies are carried out to establish this transport method in every countries.In Japan, studies on this method have been carried out for several years in laboratory and coal mines and hydraulic transport equipments which able to transport the coal about 100t per hour from underground of about 450m deep was constructed this year.

    The authors have engaged in the studies on the air pollution in Kawasaki City for the past thirty months.The following is the summary of the investigation.
    1)In the south seaside industrial area of the city, there are power plants and many other factories.The most frequent wind direction in summer is S-SSW and that in winter is N-NNW.Thus, it is clear that in the summer dust and soot fall mostly in the urban area and that in winter, most of them are driven over the sea area.
    2)There are remarkable regional differences in composition of deposited matter and these are chiefly due to the amount of insoluble substances, especially of ashes.
    3)In industrial area, there is a tendency for deposited matter to decrease recently, but in other area the rate of deposition is not decrease: these results may be due to the fact that most collectors already installed are cyclone-type, which are insufficient for collecting fine particles in fly ash.It is therefore needed more collectors as high effic-iency as electric precipitator
    4)At most places, significant correlations between deposited matter and wind direction were obtained, so that the contribution of the special source was estimated.
    5)Rainfall is more closely correlated with soluble deposit and up to 46% of the dissolved matter is brought into the deposit gauges by rain.The insoluble matter is affected little by rain.
    6)By studying the irregular month-to-month variations of deposited insoluble matter, coal burned, and most frequent wind direction, it was estimated that installation of dust collectors resulted in diminishing the amount of deposited matter.

    The authers determined the volatile matter of various solid fuels by the nitrogen-tube method specified in B.S.1016-1942, by changing the temperature at which the heating was begun under the condition of the same heating rate as specified above.
    (1)In the case of anthracites and cokes, volatile matter has no relation with the change of the temperature at which the heating is begun, and the results of the determinations under the condition as described above are nearly constant in each fuel and agree with that by the crusible method, too.
    (2)In the cases of non-caking and weakly caking coals, volatile matter increases line-arly with the rise of the temperature at which the heating is begun, and in the most cases a significant deviation is found between the results by the specified n.t.method and by the rapid heating n.t.method.And generally the result by the latter agrees with that by the crusible method.The specified n.t.method should not, therefore, be availed in these cases.The authers found, however, a modified n.t.method which could eliminate the deviation by extrapolation and give an approximate value to the result by the rapid heating method.
    (3)In the cases of caking coals, the n.t.method is not suitable.By the way, we found that the caking power and swelling power of coal were largely effected by the temperature at which the heating was begun.
