It is interesting to note the spread of weeds in a new 

 State. Saponaria vaccaria is found along the railroads, to- 

 gether with Anthernis cotula, over the whole of eastern 

 South Dakota. The former has even followed up the 

 freighting trails over the range between Pierre and the 

 Black Hills, where it is quite common, particularly at 

 watering and camping j)laces. Man is evidently the one 

 who is responsible for the distribution of this weed. 



the localities in the Eastern States, as well as those in 

 Indiana and Illinois, having been verified in past years; 

 but the localities in Kentucky and Kansas require con- 

 firmation, and that in Colorado is extremely doubtful. 



NOTES AND NEWS. 



PERIODICAL CICADA. 



BY C. V. KILEY, UNITED STATES DEPAKTMENT OF AGEICDLTXJBE, 

 DIVISION OF ENTOMOLO&y, WASHINGTON, D. C. 



Dui;iNG the present year two broods of the Periodical 

 Cicada, or so-called "Seventeen-year Locust" ( Cicada sep- 

 tendecim L.), one of the seventeen-year {septendecim) race, 

 and one of the thirteen-year {tredecim) race, will make 

 their appearance in different parts of the country. 



The following list of localities has been jjrepared from 

 previous records. Any evidence giving the extent of ter- 

 ritory over which they appear in any county or state, or 

 any well-attested dates of their appearance in previous 

 years, will be thankfully received and appreciated. 



BROOD XVL— Tredecim— (1880, 1893.) Alabama— 

 Lowndes County. Georgia — Cobb and Cherokee Coun- 

 ties. Tennessee — Lincoln County. North Carolina — 

 Lincoln and Moore Counties. This brood is but little 

 known, and all localities require further confirmation this 

 year. 



BROOD XL— Septendecim— (1876, 1893). North Caro- 

 lina — Prom Raleigh, Wake County, to the northern line 

 of the State; also in the counties of Rowan, Davie, Cabar- 

 rus and Iredell. Virginia — From Petersburg, Dinwiddle 

 County, to the northern line of the State; Bedford and 

 Rockbridge Counties; Valley of Virginia, from the 

 Potomac River to the Tennessee and North Carolina 

 lines. District of Columbia — Woods north of Washing- 

 ton. Maryland — Southern half of St. Mary's County. 

 Kentucky — Trimble County. Indiana — Knox, Sullivan 

 and Posey Counties. Illinois — Madison County. Kansas — 

 Dickinson and Leavenworth Counties. Colorado — Chey- 

 enne Canyon. This is a weU-established brood, most of 



In this age of rapid advancement in all lines of 

 knowledge, especially in science, people have learned that , 

 combined organized labor accomplishes far more exact re- 

 sults than individual effort. Every dejjartment of science 

 has its -organization for the promotion of that science. 

 Such an organization is the Wilson Ornithological chap- 

 ter of the Agassiz Association, for the promotion of ./bneri- 

 can ornithology. It is composed of active, associate and_ 

 honorary members. It is in no respect a rival of the 

 American Ornithologists' Union, but has its work con- 

 ducted on a cooperative plan, and therefore necessarily 

 largely systematic. TN hile furnishing the more 

 advanced with ample material for work, it also offers 

 such op23ortuuities to the younger and less experienced 

 as are best suited to their needs. It seeks to educate 

 those just beginning and those pursuing a dilatory course 

 into the highest usefulness as working ornithologists. 

 Active members pay an initiation fee and a yearly as- 

 sessment of SI. 00, and are limited to 100 in number. 

 This number is now nearly reached. Associate members 

 pay a yearly assessment of 50 cents and are unlimited in 

 number. All working ornithologists are invited to join 

 and aid in the work. Applications for membership should 

 reach the President or Secretary before Sept. 20, to in- 

 sure insertion in the list of candidates for the October 

 election. Address either W^illard N. Clute, Sec, Bing- 

 hampton, N. Y., or Lynds Jones, Oberlin, Ohio. 



— William Beverley Harison j)i-iblished on the 15th 

 "The Foreigner's Manual of English." This is prepared 

 for use in mixed classes of foreigners, and can be used 

 without any knowledge of the several languages, as Eng- 

 lish only is used throughout. It has been carefully cor- 

 rected to embody all of the suggestions of Gouin, whose 

 book ajDpeared after completion of first MS., and during 

 revision the MS. has been successfully used in teaching 

 Chinese, Polish Jews and others absolutely ignorant of 

 both written or spoken English. The lessons are ar- 

 ranged to give in each a concrete subject, and a useful 

 vocabulary is given to enable the student to talk from the 

 beginning. 



— The Chain Hardy & Comj^any, Denver, Colo., have 

 just ready the revised and enlarged edition of the "Geol- 

 ogy of Colorado and Western Ore Dej)osits." This work 

 of Professor Lakes, of the State School of Mines, has al- 

 ready run through one edition as applied to Colorado. 

 Now that the Western States have been included the sale 

 is ex23ected to be quite extended. The plates illustrating 

 the geological formations are very elaborate, and illus- 

 trate the peculiarities of veins and ore deposits. The 

 book is designed for a text-book, and is also adapted for 

 general reading by those interested in mining. 



— Rand, McNally & Co. have in ,prej)aration the Pro- 

 ceedings of the Bankers' and Financiers' Congress held in 

 Chicago from June 19 to 24. 



— The Scientific Publishing Co. have just ready a work 

 on "Universal Bimetallism and an international monetary 

 clearing house, together with a record of the world's 

 money statistics of gold and silver," etc., by Richard P. 

 Rothwell, editor of the Engineering and Mining Journal. 



— Macmillan & Co. have just ready "A Treatise on the 

 Theory of Functions," byTProf. James Harkness, of Bryn 

 Mawr College.
