the nearly eastern-central part of the state, 

 about six miles northwest of Boston, with which 

 it is connected by an electric line. The city 

 is also served by the Boston & Maine Railroad. 

 Arlington was a part of Cambridge from 1635 

 to 1807. In 1762 it was made a "precinct" of 

 Cambridge under the name of Menotomy; it 

 became a separate township under the name 

 of West Cambridge in 1807, and its name was 

 changed to Arlington in 1867. The area is a 

 little more than five square miles. 



The city is an important center for market 

 gardening. The principal manufactures are 

 piano cases, picture frames and ice-cutting 

 tools. Its fine library was the gift of Mrs. Eli 

 Bobbins; the high school was erected in 1915 

 at a cost of $225,000, and the Arlington town 

 hall, built in 1914, cost $385,000. Several sana- 

 torium located at Arlington Heights suggest 

 an ideal health resort. Sky Pond is one of the 

 most picturesque bodies of water in the vicin- 

 ity of Boston. H.C.L.

in the United States, at Arlington, Va. About 

 18,500 soldiers and sailors of the War of Seces- 



sion and the Spanish-American War, including 

 a number of high military rank, lie in graves 

 surrounding the fine colonial mansion which 

 was once Robert E. Lee's home, but which was 

 seized by Federal troops during the War of 

 Secession. Headstones and monuments in Ar- 

 lington cemetery can be seen from the Wash- 

 ington Monument and other elevated spots in 

 Washington, D. C., which lies just across the 

 Potomac River. 



The village of Arlington is five miles north- 

 west of Alexandria and three miles from Wash- 

 ington. It can be reached from those cities 

 by electric railway, but tourists unacquainted 

 with this fact pay two dollars for the trip by 

 automobile. 



ARM, the term generally applied to the 

 upper limbs of the human body. Strictly 

 speaking, the arm is that portion of the upper 

 part of the body which extends from shoulder 

 to elbow, the portion from the elbow to the 

 wrist being called the forearm. This distinc- 

 tion, however, is not usually observed, and

when the arm is spoken of the entire upper 

 limb above the hand is meant. 



The arms in man, not being needed for 

 walking as in the case of many animals, have 

 been developed for a number of higher uses, 

 their great freedom of motion making this 

 possible. Though used by primitive man only 

 for climbing, seizing food, preparing it for use 

 and conveying it to the mouth, and for pur- 

 poses of attack and defense, the steady for- 

 ward march of science and invention has vastly 

 broadened their usefulness. The arms are also
