18 EXPEBIMENT STATION RECORD. 



In 2S cases tho greatest yield corresponded to planting at the time of the new 

 moon, 29 to planting in the first quarter, 28 at the time of the full moon, and 

 27 in the last quarter, there apparently being no material difference to be at- 

 tributed to the influence of the moon.

 Weather Bureau library and of recent papers on meteorology and seismology,

Meteorological observations (Michigan Sta. Rpt. 1910, pp. 187-200). — Tabu- 

 lated daily and monthly summaries are given of observations during 1909 at 

 East Lansing, Mich., on temperature, pressure, precipitation, cloudiness, wind 

 movement, etc. 



Note on the amount of silt carried by the Nile during the floods of 1908 

 and 1910, F. Hughes (Cairo Sci. Jour., 5 (1911), No. 53, pp. 29-36').— This 

 article reports and discusses results of silt determinations in samples of flood 

 waters of the Nile collected near Cairo and from other parts of the river and 

 in some of the irrigation canals, the object being to ascertain the variation in 

 the amount of suspended matter at different depths in the water and at different 

 points in the course of its flow, and thus to show what part of the suspended 

 matter reaches the land under the present conditions of ];)erennial irrigation. 



The results " demonstrate very clearly that the loss of suspended matter as 

 the water traverses the canals and miskahs is very largely confined to the 

 coarser material and as a result the deposit which reaches the land under the 

 present system of irrigation has a tendency to form a heavier soil than that 

 which would be obtained by the basin system. In this latter, almost the whole 

 of the suspended matter is left on the land and the small part which may escape 

 deposition consists of the very finest of the material. Its quantity is, however, 

 very small." 



The artesian water supply of eastern Florida, E. H. Sellards and H. 

 GuNTER (Fla. Geo!. Survey Ann. Rpt., 3 (1910), pp. 77-195, i)ls. 6, figs. 11).— 

 This is a second paper on the water supply of Florida, the first dealing with 

 the underground waters of central Florida (E. S. R., 19, p. 313). 



It is stated that there are three principal areas in which flowing wells are 

 found in Florida, namely, the Atlantic coast area, the Southern Gulf coast area, 

 and the Western Gulf coast area. The Atlantic coast area is described in detail 

 in this report. " This flowing area includes much of Nassau and Duval coun- 

 ties, and with the exception of local elevated areas all of St. Johns County; it 

 follows the valley of the St. Johns River almost if not quite to the head waters, 

 while a narrow strip reaches south along the Atlantic coast for 250 to 300 

 miles." 



A brief account is given of the geology and soils of the region.
