110 EXPERIMENT STATION RECORD. 



"It would seeiii tlint these precautious Khould 1)0 sufficient to prevent injury, 

 unless it l>o in tlie case of narrow valleys, where the cold nir from the unprotected 

 hillsides displaces that which has been kept warm, and, should Avind-breaks be 

 ionnd successful in removing this danger, it is believed that there are few, if any, 

 loialities where injury could not be avoided." 



Departiiresj from normal temperature and rainfall, v^rith crop 

 yie'ds, in Nebraska, H. U. C. Dunwoody ( U. S. I)ept. Afjr., Weather 

 Bureau, pp. 30, charts 10). — This is a series of diagrams accompanied 

 by explanatory notes "exhibiting the departures from normal tempera- 

 tare and rainfall, and also the variations from the average yield of corn, 

 wheat, oats, potatoes, and hay in ^Nebraska for each year from 1880 to 

 1895, inclusive. . . . 



"In the construction of the diagrams, data have been used from 8 

 stations so distributed as to best represent the actual conditions which 

 existed over the central and eastern portions of the State, the most 

 important agricultural districts. 



"With records presented in this form, the farmer may compare the 

 current weather conditions, as the season .advances, with the corre- 

 sponding periods of previous years, and thus be enabled to determine 

 some time in advance of harvest the i)robable effect upon his crops." 



Climate and Health, W. F. R. Phillips ( U. S. Ihpi. Afjr-, Wcaihcr Bureau, Climate 

 and HeaUh, ;? ( IS96), No. 1, pp. 3J, charts 14). — "Climate and Health is intended to be 

 a repertory of statistical and other information appertaining to climatology and its 

 relations to hygiene, from which persons interested in the subject of the influence of 

 climate and weather upon health may obtain data for making comjiarisons to deter- 

 mine the relative therapeutic and hygienic merits of dili'erent climates, for the prose- 

 cution of original researches, and whatever other uses and purposes to which they 

 may find the inibrmatiou applicable . . . 



"This number contains cliraatologic, morbidity, and mortality statistics for the 5 

 calendar weeks emljraced between December 29, 1895, and February 1, 1896, inclusive. 

 The climatologic statistics are taken from reports of the regular stations of the 

 Weather Bureau, and the morbidity and mortality statistics from special reports con- 

 tributed by physicians and health officers directly to the Weather Bureau." 



A scientific lightning rod, W. A. Anthony (Rural New Yorker, 55 {1896), No. 

 2432, p. 597). — The author recommends for a ground connection in moist earth a 

 plate of copper or galvanized iron iiresentiiig a surface of 6 or 8 sq. ft., with the 

 end of the rod wired and firmly soldered to it. The rod itself would best be a 

 cable of copper or galvanized ii'on wire. Size of conductor will depend on exposure 

 and surroundings. For an isolated building on au elevation, with no trees near, -^ 

 in. gahanized iron cables would suffice, and enough of them should be used to 

 furnish an ample path for any possible discharge. They should all be connected, 

 the sharp points of the upper end extending above chimneys. No insulators should 

 be used. 



Meteorological observations, L. Metcalf and J. L. Bartlett (Mafisachiisells 

 Hatch Sta. Mit. Jiuh. S8 and SO, pp. 4 each). — The usual summary of observations at 

 the meteorological observatory of the station during April and j\Iay, 189(5.

 •pp. 449-487, charts 7, pi. 1). — Besides the usual summnries of observations at over 

 2,500 stations, No. 10 contains special articles upon the earthquake of October 31, 

 1895, by C. F. Marvin; ])hotographing lightning by daylight, by A. .1. Henry; and 

 notes by the editor on the great storm of October, 1896, in the Gulf of California,
