The pine caterpiller,Dendrolimus punctatus Walker, has the habit of leav-ing the crown part of a tree and hibernating under the loose bark of thetrunk. The present paper reports the successful control of this pest by treatinga part of the trunk with a DDT suspension. All experiments were carried outat Nanking, 1947-48. When solutions and water suspension containing 5% DDT, 1%γ 666,or 5% 1068 were applied with a brush to the trunk for a width of one footand over-wintering larvae were allowed to crawl over the treated area, all theinsecticides tested were found to be effective when freshly applied. After oneweek, how-ever, only preparations containing DDT remained effective. DDTwater suspension was markedly better than DDT in kerosene, soybean oil, oracetone. Trees treated with a 5% DDT water suspension were still very toxic tothe caterpillars at the end of six weeks. The number of caterpillars crawling over a DDT-treated area would notinfluence the toxicity of the DDT film under practical field conditions. In oneexperiment all area of twenty inches square, treated with a 5% DDT suspension,still showed high toxicity to the caterpillars after 1,800 larvae had crawled overthe area in a period of nine days. Caterpillars were found to be more resistant to DDT in summer than inwinter. By increasing either the concentration of DDT to 10-15% or thewidth of the treated area to 2-3 feet, the "trunk treatment method" could beused as well in summer, if the caterpillars were beaten down to the grounedafter the trees had been treated with DDT. Under the field conditions in Nanking, 1947-48, the pine caterpilIars beganto leave the crown part of the trees and seek hibenation quarters in November.They became active again early in March, hence tree should he treated withDDT not later than the dates mentioned above. A total of 157,658 trees were treated with DDT on the Purple Mountain,Nanking, 1948. Examinations showed that larval population decreased 90-99%in the treated area, while in the check area an increase in population of16-350% had been observed.

本文研究在松树干上涂刷有持久性的药剂以防治越冬松毛虫的可能性。1947—48年在南京试验及实施防治的结果简述如下: (一)在实验室内使越冬松毛虫爬行越过涂有一市尺宽各种药液的松树干的结果,证明5% DDT,1%γ666,与5% 1068的悬液或溶液。在涂药的当天均 有相当高的杀虫效力,惟一周以后γ666与1068完全失效,仅DDT仍保持强大的毒力。DDT水悬液显著较DDT火油、大豆油或丙酮溶液为佳。涂有5%DDT悬液的松树杆曝露田间六星期后,杀死松毛虫能力仍达100%。 (二)据试验的结果,自制的可湿性DDT,内含DDT50%,稀释剂45%,与肥皂5%,尚适宜于防治松毛虫之用。 (三)松毛虫爬行的次数对涂药面积上DDT毒力的影响极微,在二十平方市寸涂有5% DDT悬液的小面积上,9天之内经过1800头松毛虫爬行后,毒力仍未减小,死亡率尚在90%以上。 (四)夏季松毛虫较越冬松毛虫不易杀死。夏季松毛虫抵抗DDT的能力随龄期而增强。试验中显示如增加药液浓度至含DDT 10—15%,或增加涂药的宽度至2—3市尺,夏季幼虫亦能中毒死亡。故树干涂药法亦可应用在夏季防治上,惟必须在涂药后将松毛虫从树上击落,使其在爬返树冠...

In this paper we have made a study of the explicative teats of the hexagram ‘Feng’in the Book of Changes. Meantime, the written records in Chinese ancient books and the telescopic sunspot records in early Europe are examined in detail. It is proved that the written records about“to see‘dou’on the Sun”and“to see‘xing’on the Sun”essentially are the sunspot records. This displays that at least not later than 800 years B.C. the Chinese written records of sunspot started, which are the earliest in the world....

China is a large country, with abundant resources and a long history. Accord- ing to legend, in Shanxi Province, mining for copper dates as far back as 5300 years ago. It has been verified by modern archaeology that in Gansu Province copper mines and lead mines were worked not later than 4000 years ago. During the Shang Dynasty (1600 B. C. -- 1100 B. C.), extensive mining was carried out for copper, tin and lead, and covered a very broad area from Inrier Mongolia in the north to the Five Mountain Ranges in the south and from Gansu Province in the west to Shandong Province in the east. During the Western Zhou Dynasty government officials were appointed for the organization and management of the mining industry. In the earliest mining operations, stone implements were used. In the excavation of the Linxi Ancient Copper Mining Site in Inner Mongolia, more than 1060 pieces of buried stone hammers and other mining implements were found. Mining at this ancient site possibly began in the Western Zhou Dynasty and continued to the Tang and Song Dynasties. Thirty-eight open-pits were found there, the largest pit had a maximum length of more than 500 meters and a maximum depth of 17 meters. Large amounts of furnace slag were also found, indicating a comparatively large scale of operation. During the Eastern Zhou Dynasty (known as the Spring and Autumn and the Warring States Periods), the mining of iron ore became common. The Qi Kingdom carried out the policy of "nationalization of mountain and sea," which encouraged the development of mining and metallurgical enterprises, and the mining of various metal minerals became common. Some of these were recorded in detail in the ancient book "Shan-Hai-Jing" (the book of Mountain and Sea). This book recorded more than ten kinds of metallic mineral products, 176 old mining sites, and information about various types of ore deposits and metallic mineral association. This book is among the world's oldest literature on mining. Since 1974, an ancient underground copper mine of the Zhou Dynasty has been explored by excavation at Tonglushan, Hubei Province. This find has been of important significance in the study of the history of ancient mining and social de- velopment in China. At this ancient mine site many vertical shafts were sunk since the Western Zhou Dynasty. The depth of the shafts reached more than 50 meters during the Warring States Period. The hoisting, drainage and ventilation problems of underground mining were solved successfully. The windlass used for hoisting was much improved from those commonly used and more scientific. Through the development of many types of timber-sets, the ancient miners successfully overcame the difficulty of mining in fissured ground, thus greatly advancing the technique of underground mining and contributing to the development of mining in ancient China.

由近代考古工作证明,我国最晚大约于四千年前,就在现今的甘肃省开始开采铜矿和铅矿。商代(公元前1600~1100年)铜、锡、铝矿已大量开采;西周时设有矿官,负责矿业的组织管理。文章着重引证了内蒙林西露天古铜矿和湖北铜录山古铜矿井的出土文物资料,说明我国开采矿业历史悠久,古代劳动人民在采矿技术方面有很多发明创造,做出了很大贡献。
