The present paper gives a report on a study of the life his- tory of a destructive pest, Melanauster chinensis Forster, of citrus trees in Foochow during the years 1951 and 1952. It has been found that the adults lay eggs beginning from the last part of May until the end of July. Eggs are inserted in the bark of the tree trunk about 1. 4 inches from the ground. Incubation period lasts from 9 to 14 days. After hatching the young larvae feed under the bark for three or four months. In October they bore into the wood from a place about one to two inches above the ground. Overwintering of the larvae in the burrows generally begins in November or December. They resume actti- vity in March the following year. Pupation takes place abou the middle part of April. The pupal period lasts from 18 to 20 days. After emergence the adults remain in the pupal cells in the upper part of their burrows for about five to eight days. The adults appear from the middle part of May to the middle part of August. Burrows made by the larvae under the bark as well as in the wood have been studied carefully. Recommendations have been given to improve the original technique of destroying the larvae by probing with wire.

Cement plot experiment indicates that a mixture of 1 part phenyl mercuryacetate to 5 parts hydrated lime or 1: 15 and 1: 20 ethyl mercury chloride andhydrated lime applied as dust give much better control of rice blast than bor-deaux mixture.These fungicides are not injurious to rice plant except causing afew necrotic spots on the leaves. Similar results were obtained in field experiments.Plants dusted 2-3 timesduring the growing season yielded 25-158% higher than the untreated.

As in general in all time service works, the problem is to obtain and keep an accurate time, to determine the corrections of standard clock and to transmit time signals. This present report is concerned only with the last two items. At Zi-Ka-Wei Observatory, radio method was introduced into time service in 1914. Some rigorous changes occured in 1926, a number of instruments were installed. Many of them are still in use. In 1940, the observatory began to transmit rhythmic signals twice a day. From then on until December 1950, no further developments were made. The main instruments we had in 1950 were: a 80mm Prin transit with impersonal micrometer, two Leroy pendulums as standard clocks, three astronomical clocks and their slaves, equipments for receiving and recording time signals, etc. Since 1952, we began to make some improvements, especially on rhythmic signals. First, we converted a common clock into a "transmitting clock" to obtain 61 impulses in every minute and second by making use of photoelectric arrangement (Fig. 1), we succeeded to raise the accuracy of our signals. To improve signal accuracy further, we have to deal with various sources of errors which are conditioned by our equipments. The most important among these are: 1. error in prediction of corrections of the standard clocks, 2. error in the adjustment of the transmitting clock and 3. time lag in transmission. In consequence of last three-year's research, these errors are reasonably reduced. The first two are now±0~s.007 and ±0~s.005 respectively and the last is small. Accordingly, the deviation of time signals XSG has been supposed to be±0~s.01. However, this is not enough for the requirement. The more efforts are being made to bring further improvements. But as the requirements for signal accuracy is far above what the present installation can offer, some new equipments are ordered and they will joint in force with the old ones in the nearest future. Since February 1954, Zi-Ka-Wei Observatory has cooperated with the time service departments in Soviet Union. This has been helpful to our works in every way.

授時包括测時、守時和播時三个主要方面。在時號的发播中包含了预報主钟改正量的差误,工作钟的調節誤差和電路遲滯变化等三种誤差。如果使用石英钟及有關设备,这就可基本解决。各台站在其天文观测基础上订定的時號改正數也包含有偶然差和系统差,比較全面解決的只有蘇聯和国際時間局这两个标准系统。徐家匯觀象台授時工作歷史很久,作了一些工作,但抗戰以來,郎停滯不前,直到人民政府接办,才逐步在原有基礎上開展了改進。幾年来主要是改裝了一具工作钟,裝置光電设备以发播科学式時號,對時号精确度解决了秒距誤差和五分间誤差。工作钟的调节誤差被其本身品質所限,仍未解决,只是在加強值班工作之后,有了一定限度的提高,目前約為±0~s.005,在预报主钟改正量時,也有很大程度的不稳定,約為±0~s.007。所以時号的精确度在±0~s.01左右。要进一步提高质量,满足要求,有待於新設備的增添使用。在時号改正數方面,所存在的相當大的系统差,可採用蘇聯或国際時間局系統的改正數來避免。
