Ericerus pela Chavannes, the insect producing white wax,belongs to Coccidae,Homoptera. The female adult lays eggs while the male larva produces wax, whichis a well-known product from Southwest China. The wax secreted by the malelarvae may be boiled and extracted to result in something known as white wax.Its boiling point reaches above 82-83℃. It has manifold uses. Before WorldWar Ⅱ, besides the consumption at home, th greater part of this product wasexported abroad. The supply of the female adults of this wax insect in the wax-producing districtusually appears short annually, due to a peculiarity in the growth of this creature;and therefore naturally exist two correlative districts, that is a district of adultproduction and one of wax production. As these two.districts are located morethan 500 kilometres apart,every year the female adults ready to be transplantedon he feeding trees in the district of wax production have to be supplied bythe district of adult production, and they must be carried over a long distance.The carriage of the female adults of the wax insect from one place to theother has been practiced for about five hundred years by the people engaged inwax production. This article reports on a test of transportation of the female adults of the wax insect from Paikuowan (白菓湾) in Hweili County (会理县), formerly of SikangProvince to Huhtaokou (核桃沟) in Omei County (峨眉县), Szechwan Province.Investigations in this connection were made from the April 30 to May 13, 1941. It has long been the aim of the growers to produce the female adults of theinsect and the wax in the same locality. With this realized, the area of wax pro-duction would be enlarged, and the quantity of wax increased. However, as the female adults of the insect in the distr .ct of wax produc-tion are subject to such natural adversities as geographical features, temperatureand humidity, parasitic enemies etc., up to the present they cannot be raised andsapplied insufficient quantity in this district. For this reason, to in prove themethod of transporting the adults female insects to the wax-producing district, toShorten the time on the way,and to increase the vitality of the male larvae-all these have become the crucial questions in the promotion of wax production. The principal explanation, knowh for centuries, with regard to the impossi-bility to raise the female adults of the insects in the district of wax productionhas been the peculiar fact that the female larvae could not be carried in quickorder to a place over 500 kilometres apart. The present test has proved that al-though the female larvae were, in the greater part, hatched out on the way, therewere still a part of them reaching the destination in safety. Valuable informat-ion was also obtained on the hatching rate of the male and female larvae on theway, the influence of environmental factors on the sex ratio, the different speciesof parasitic enemies, etc.. It is hoped thet the facts thus ascertained will be ofservice to improving the methods of wax production.

白蜡虫是我国的特产,古代农民远在元朝已有饲养。在过去全国的白蜡年产量约在五万至十万担间,据1918年重庆海关报告有一万一千余担,值银七十七万余海 关两。解放前一、二十年来,由于国民党反动派的不重视和摧残,已逐渐衰落。白蜡是化学工业上的重要原料,用途很广,饲养蜡虫又是西南各省农民的主要副业,而且农民群众已积累了非常丰富的传统经验。因此,为了总结群众经验,发扬科学遗产,改进饲养技术,振兴蜡业,我们希望能引起有关方面的注意和进一步研究,除研究改进白蜡虫的经管技术外,又须注意白蜡在工业上的用途。 白蜡虫的种蜡异地繁荣,在目前已成为自然的形势,而蜡区种虫不能自给,是白蜡业发展上的基本障碍。我们通过本次测验之后,认为我国适于蜡虫(雄虫)繁育的地方很多,如四川、湖南、浙江、安徽、福建、江西、江苏等丘陵地带都可扑虫产蜡,关键问题在于改善运种方法。在目前我国交通运输业已有普遍发展的基础上,只要用航空运种即可在短时间内将种虫运送至全国蜡区。扩大蜡区,增加农民副业收入,发扬我国科学遗产,为国家创造财富,利用益虫为生产服务,在目前已完全有实现的可能。

Coilia mystus (L.) is a small fish of economic importance, belonging to the Family Engraulidae. It occurs abundantly along the coast of Amoy and vicinity. The present investigation was undertaken with the chief object of finding out the compostion of food and its seasonal variation. A total of 612 stomachs were examined; of these, only 22 stomachs were found to be empty. The following are the results of the investigation:(1) Coilia mystus feeds chiefly upon planktonic Crustacea, of which Copepoda is, by far, the most important, constituting no less than 75.9% of total food. Of the 15 species of Copepoda identified, Paracalanus pqrvus, Pseudodiaptomus marinus and Tortanus forcipata are relatively more important than the others. Among other Crustacea, the relative importance of various groups Is of the following order: Decapoda (including Lucifer and Brachyuran larvae) > Mysidae > Euphau-siacea > Amphipoda > Ostracoda > Cumacea > Stomatopoda. Next to Crustacea in the order of importance of food conic Chaetognatha and fish ova, the former being the more important of the two. Judging from the composition of food, Coilia mystus is a plankton-feeder.(2) The composition of food is more or less subject to seasonal variation. The order of numerical importance of various groups* in the four seasons is as follows: SPRING (Mar.-May): Copepoda > fish ova > Decapoda > Amphipoda > Mysidae> Euphausiacea > Cumacea> Stomatopoda, young fish. SUMMER (Junc-Aug.): Copcpoda> fish ova> Decapoda >Mysidae> Amphipoda> Euphausiacea > Cumacea > young fish.AUTUMN (Scpt.-Nov.): Copepoda > Decapoda > Mysidae > Ostracoda > Euphausiacea > Amphipoda > Stomatopoda > young fish.WINTER (Dec.-Feb.): Copepoda > Decapoda > Euphausiacea > Cumacea > fishova > Mysidae > Amphipoda > young fish > Stomatopoda. (3) The composition of food varies with age or length (from the tip of snout to the end of body, exclusive of caudal fin) of fish which appears to he related to the density of gill-rakers. The younger fishes (less than 15 cm. in length) with denser gill-rakers (2.0-2.7 rakers per 1 mm.) feed largely upon smaller crustaceans (Cope-poda); whilst the older fishes (over 15 cm. in length) with sparser gill-rakers (1.4 1.9 rakers per 1 mm.) feed largely upon larger crustaceans (Mysidae, Euphausiacea, Stomatopdda, Decapoda). It shows that increase in the size of fish is associated with increrase in the size of food animals eaten.(4) There exists a fairly close agreement between the composition of food and the composition of plankton in the surrounding waters. During the months of March and November when both fish and plankton were collected at the same time off Hai-Chen near Amoy, Copepoda was found to be the most dominant group in both food and plankton. It shows that the fish fed heavily upon those crustaceans occurring most abundantly in the plankton. In this respect, Coilia mystus exercises no selectivity of food. The writers are of the opinion that abundance and availability rather than selection by the fish determine the species of animal eaten.(5) A comparison of the food of Coilia mystus with that of other Clupeoids in Amoy waters reveals the predominance of Copepoda in the diet of most of these fishes. For the sake of increasing the yield of these economic fishes, it is essential to enhance the production of Copepoda in nature by artificial means such as to fertilize the water with nutrient salts, especially phosphates and nitrates, to increase the production of phytoplankton which will, in turn, lead to the higher production of Copepoda.

The object of this paper is offer an analytical method for solving the very important stereo-bridging problem in photogrammetry. In solving this problem we suppose that at the beginning and at the end of an arbitrary photo-strip there are three ground control points having their immages on the corresponding two pairs of photographs respectively. Based upon this condition we can utilize the stereo-resection method to carry out the aerial triangulation throughout the entire strip in order to get enough space intersection points for each intermediate photograph possibly to be mapped by virtue of some simple instruments.This paper is the extension of a previous article entitled "Photogrammetric Space Resection", published in the Chinese Journal of Civil Engineering, Vol. 1, No. 4, Dec., 1954. At present, as the writer has not get gone so far into numerical computation, how would this method be workable is subject to test in the near future. The prospect of not only furthering the theoretical foundation of photogrammetry but also opening a new approach to the photomapping problem is highly encouraging.
