having been raised, the author states that as this compound contains about 4 

 times as much copper as is present in copper sulphate, less of it can and should 

 be used. Any copper present on the grapes, he says, would be precipitated in the 

 wine as an insoluble sulphid through the sulphuretted hydrogen liberated during 

 the fermentation. In a similar manner he claims that barium chlorid may be 

 substituted for arsenic compounds used as insecticides, the barium being rapidly 

 precipitated in an insoluble form during the fermentation of grapes in the 

 process of wine making. 



Testing powders of sulphur and sulphur-copper sulphate mixture for use 

 in vineyards, J. Slaus-Kantschiedeb {ZtscJir. Landw. Versuchsiv. Osterr., i) 

 (1911), No. 12, pp. 1378-13S3) .—Detailed directions are given for the employ- 

 ment of the Chancel method for determining the fineness and consequent value 

 of the powders to be used and the percentage of copper sulphate in the mixture. 

 The mixture should be employed when Peronospora is present on the vines in 

 addition of Oi'dium, but the powdery mildew when alone is best combated by the 

 application of sulphur reduced to an impalpable powder.

A note on a peculiarity of plague on the Hamakua Coast of Hawaii, G. W. 

 McCoy (Pm.6. Health and; Mar.-Hosp. Scrv. U. 8., Pub. Health Rpts., 27 {1912), 

 No. IJf, pp. '189, 490). — It is stated that at present this disease occurs rather 

 extensively among rats on the north coast of the island of Hawaii, known 

 locally as the Hamakua Coast. " It seems clear that, regardless of the direct 

 mode of infection, rj'.ts are the primary source of the human cases, as large 

 numbers of plague-infected rats are being taken on the Hamakua Coast." 



New state quarantine law {Mo. Bui. Com. Hort. Cal., 1 {1912), No. 2, pp. 

 42-44). — The text of the quarantine law of January 2, 1911, is presented. 

 This act prohibits the introduction of insects, diseases, or animals, injurious to 

 fruit or fruit trees, vines, bushes, or vegetables, and provides for a quarantine 

 for its enforcement. 



A history of the birds of Colorado, W. L. Sclateb {London, 1912, pp. XXIV-r 

 576, pis. 18). — This volume is said to be founded upon the very complete col- 

 lection of Colorado birds formed during the last 35 years by C. E. Aiken, of 

 Colorado Springs, and which was recently presented to the museum of Colorado 

 College. The author gives keys to the orders, families, genera, and species of 

 birds that occur in the State. In additon to references to literature, descrip- 

 tions, and distribution, the habits of many of the species are considered at con- 

 siderable length. 



The number of Colorado birds included in the work is 392, of which 225 may 

 be considered regular breeders within the State. Sixty-seven are resident 

 throughout the year, 118 are strict migrants which, so far as known, never 

 winter within the limits of the State, and 40 are birds which breed within the 

 State but in winter are imdoubtedly less numerous, so that they may be con- ' 

 sidered partly migrant and partly resident. Of tlae 167 nonbreeding birds, 106
