European languages, and was produced in sev- 

 eral continental cities. 



In 1900 Cyrano and L'Aiglon, another of Ros- 

 tand's plays, were presented in America by 

 Sarah Bernhardt and Coquelin. Richard Mans- 

 field produced Cyrano in English in the United 

 States and Canada. A Chicago business man 

 named Gross filed suit against Rostand, claim- 

 ing that Rostand's play was a plagiarism of 

 his own comedy, The Merchant Prince oj 

 Cornville. Gross won the suit, and Cyrano 

 de Bergerac had to be withdrawn. Rostand 

 has written several other plays. His most con- 

 spicuous success after Cyrano was Chantecler, 

 a fantasy of bird and animal life which was 

 awaited with great interest and hailed with en- 

 thusiasm both in France and in America, where 

 Maude Adams appeared as "Chantecler." Ros- 

 tand was elected to the French Academy in 

 1902. 



ROS'THERN, a town in the central part of 

 Saskatchewan, and on the Canadian Northern 

 Railway about midway between Prince Albert 

 and Saskatoon. It is forty miles north of 

 Saskatoon and forty-seven miles south of Prince 

 Albert. Rosthern is situated in one of the 

 richest wheat-growing areas in the world, a dis- 

 trict made famous by Seager Wheeler, the 

 world's champion wheat grower, who lives four 

 miles from the town. Rosthern's five elevators 

 are among the largest west of Winnipeg. 

 Flour milling is the only important industry. 

 Rosthern was settled in 1896, and was incor- 

 porated in 1906. The attractive town hall, 

 built at a cost of $30,000, was completed in 

 1909. Nearly half of the residents of Rosthern 

 are of German birth or descent. Population 

 in 1911, 1,172; in 1916, about 1,400. 



ROSTOCK, rohs'tohk, one of the busiest 

 German porta on the Baltic, and the largest 

 i of Mecklenburg-Schwerin, is situated on 

 the Warnow River, about eight miles from the 

 sea. No other Baltic port possesses so large 

 a merchant fleet. Although the city has a 

 medieval appearance, its busy fairs for the ex- 

 change of wool, horses and cattle are thor- 

 oughly modern in spirit. The industries arc 

 (1, the most important being shipbuilding, 

 ill- making of machinery and chemicals, brew- 

 ing and di-fillmn. Rostock is the seat of tin- 

 -Mi'irmc court of both the duchies of Mecklen- 

 burg, and is well supplied with schools, hos- 

 !-i' ils and other institutions. Among the most 

 i tit. resting of its buildings are Saint Mary's, 

 one of the finest Gothic churches of Northern 

 Germany, the ducal palace, the Gothic town 



hall, with its many turrets, and the new uni- 

 versity building. A statue of Bliicher, who was 

 born here, adorns one of the city's many fine 

 squares. The university was founded in 1418 

 and rebuilt in 1867. It has a library of 140,000 

 volumes, an observatory, and an experimental 

 agricultural colony. Population of the city in 

 1910, 65,377. 



ROSWELL, rahz'wel, N. M., the center of 

 one of the largest cattle and sheep-raising sec- 

 tions of the United States, and the county 

 seat of Chaves County, is situated in the south- 

 eastern section of the state and on the Pecos 

 River. Amarillo, Tex., is 212 miles northeast 

 by rail, and El Paso is 230 miles directly south- 

 west. Transportation is provided by the Atchi- 

 son, Topeka & Santa Fe Railroad, constructed 

 to this point in 1900. The most important 

 industry of the place is the raising of cattle, 

 sheep, alfalfa and apples. The county court- 

 house, constructed at a cost of $161,000, the 

 $115,000 Federal building, the New Mexico 

 Military Institute, Saint Mary's Hospital, the 

 Carnegie Library and a high school are features 

 of interest in the city. Although the place was 

 settled in 1877, it did not become a city until 

 1903. In 1910 the population was 6,172, about 

 five per cent of the inhabitants being Mexi- 

 cans and negroes. 



ROTATION, rota' shun, OF CROPS. Agri- 

 culturists have found that raising the same crop 

 on a field, year after year, deprives the soil of 

 its fertility, no matter how deep and rich the 

 soil may be. An experiment conducted by the 

 Illinois Agricultural Experiment Station affords 

 a striking illustration of this fact. A record of 

 the crops grown during a period of twenty 

 years shows the following results: One plot 

 was kept in corn for the entire period; on an- 

 other, corn and oats were grown in rotation; 

 on the third, clover was added to corn and oats. 

 On the first plot, the yield at the end of the 

 period was twenty-nine bushels to the acre; on 

 the second, forty-eight bushels, and on the 

 third, eighty bushels. At the experiment sta- 

 tion of Tennessee it was shown that, under a 

 proper system of farming, the productivity of 

 the soil was increased from twenty to eighty 

 bushels an acre. 



All fertile soil contains available plant foods 

 nitrogen, potash and phosphorus in varying 

 proportions, and also a sufficient amount of 

 r to dissolve these foods and supply them 

 to the plants as fast as they are needed. One 

 plant requires a larger proportion of some of 

 these foods than another, and if that plant is
