the world. The perfect insect is a yellowish- 

 brown moth, marked on each fore wing with a 

 white spot. It flies at night and may be 

 caught in large numbers around lights or by

baiting with syrup. It lays its eggs in strings 

 of from two to twenty, beneath the sheaths of 

 grass stems. The caterpillar continues to grow 

 for three or four weeks after hatching and then 

 the insect goes into the ground for its inactive 

 pupa stage. 



The army worm is best known east of the 

 Rocky Mountains, but it is usually so well 

 controlled that no serious damage is done by it. 

 When these insects appear in large numbers 

 the field should be plowed or the crop burned. 

 They can be destroyed by Paris green mixed 

 with soap suds or by a kerosene emulsion, but 

 they are most effectively destroyed by other 

 insects which feed upon them, especially by the 

 tachina fly. 



ARN'HEM or ARNHEIM, am 1 hime, a town 

 in Holland, capital of the province of Gelder- 

 land. It is situated in one of the most beauti- 

 ful districts of Holland, on the right bank of 

 the Rhine, 35 miles southeast of Utrecht. The 

 ramparts surrounding the older portion of the 

 city, called Arcnacum .by the Romans, have 

 been made into beautiful promenades. The 

 city has many fine buildings, the most noted 

 being the town hall, which is popularly called 

 the Devil House, because of its weird decora- 

 tions. Its principal church contains the tombs 

 of the former Duke of Gelderland, who made 

 the city their place of residence. 



The manufactures consist of wagons, furni- 

 ture, mirrors and scientific instruments, and 

 tobacco and grain are exported. During the 

 Middle Ages Arnhem was a member of the 

 Hanseatic League. In 1795 the city was taken 

 by the French, who were driven out by the 

 Prussians in 1813. Population, 65,685. 



THE ARNICA PLANT 



ARNICA, ar'nika, the name of certain 

 plants which yield a juice or a tincture known 

 to every child, be- 

 cause it is used on 

 bruises to drive away 

 the blood which col- 

 lects around them. 

 The common or 

 mountain arnica is 

 found in Central 

 Europe and in the 

 western part of the 

 United States. It has 

 a twisted root which 

 lives from year to 

 year, and a stem 

 about two feet high 

 which bears heads of 

 golden-yellow flowers. 

 Every part of the 

 plant contains the 

 arnicin, of which the 

 valuable medicine is 

 made. 



AR'NO, a famous river in Tuscany, Italy, 

 on whose banks stand Florence and Pisa, the 

 former fifty miles from its mouth, the latter 

 only six. Its source is in the Apennines, 4,430 

 feet above the sea and its mouth on the coast 

 of the Ligurian Sea, the arm of the Mediter- 

 ranean Sea north of Corsica. When the water 

 is high boats may ascend the Arno as far as 

 Florence, and in the Middle Ages Pisa was 

 a maritime port of the first rank. The river 

 valley, which bears the musical name Val d' 

 Arno, is one of Italy's fairest regions. The 

 total length of the river is about 150 miles. 



ARNOLD, BENEDICT (1741-1801), an Amer- 

 ican general of the Revolutionary period, a 

 brilliant man, for long beloved and trusted, 

 yet whose ambi- 

 tion finally led 

 him to betray his 

 country. After 

 his act of treach- 

 ery, those who 

 were seeking his 

 arrest for treason 

 said that it would 

 be right to "bury 

 with high military 

 honors the leg 

 which was in- 

 jured at Saratoga 

 and Freeman's Farm and hang the rest of him." 



Arnold was born in Norwich, Conn. He re-
