31 species, 5 genera of Drosophilidae had been obtained on 11 localities of Seoul and its adjacent and during the period of May ∼October, 1957. The species which distributed widely were Drosophila (Sophophora) quraria, D.(drosophila) angularis D.(D.) brachiynephros, D/(D.) nigromaculata, Scaptomyza disticha and D.(Sophophora) melanogaster. The localities where relatively many species of Drosophilidae were collected were Kwang Neung (25 species, 4 genera) and Sosa(13 species, 2 genera)

The collections of Drosophilid filies were made for this stduy in three localities (Kwang-nung in Kyung-ki province, Chae-ju Island, Yong-Moon in Kyung -Ki province), during a period from April to October, 1959. Total specimens 7857 collected at these areas were classified into 7 genera, 67 species. Among these species, 5 genera, 17 species are unrecorded species Drosophilidae of Korea.

The seasonal and altitudinal changes in distribtuion of three selected species of wild Drosophila populations ; D.(S.) auraria , D.(D,) transversa and D.(D.) lacertosa growing at Mt. Sori in Kwang-nung (Kyung-ki province, Korea) were surveyed from April to November in 1959. The field of observations ranged in altitude from 150 to 450 meters. Each of selected species were found in different altitudes with no significant level. D.(S.) auraria were found with numerically dominance in April and were found in June with less superiority. D.(D.) transversa showed their highest peak in numerically in May and after soon they decreased, in August they made the lower peak again. Author could drow in June the highest peak shown D.(D.) lacertosa's distribution and then the line was down to November smoothly.

Leachates resulting from the waste landfill of waste can possibly cause the second pollution, such as the underground water and environmental pollution. Accordingly, Liner layer has been installed in the reclaimed land of waste to block and purify permeation water to and prevent this second pollution. The material used as Liner layer should have water resistance and be less than permeability coefficient of $1{\times}10^{-7}$ cm/sec. As it is very difficult to get this kind of natural clay with low permeability around the field, the suitable way to get the low permeable material is to use blend with good watertighness by mixing it with natural soil which is spread in the site. While this mixed soil, which can resist water, is commonly used in the site, namely, bentonite and MCG cementious mateiral mixed soil, which is widely used as Liner layer in the reclaimed land of waste, is recognized in Liner and durability. The study was performed to find the effect of additive of the bottom liner in the waste landfill. The aim of this paper is to explain of the field application examples as well as the data of experimental research with the engineering properties of Liner layer of the reclaimed land.
