LONGITUDE 



Long Island Sound, an arm of the Atlantic 

 Ocean, 110 miles long and from twenty to 

 twenty-five miles wide, which separates West- 

 chester County, New York, and the state of 

 Connecticut from Long Island. It is connected 

 with upper New York Bay by the East River, 

 and is fed by the Thames, Housatonic, Mystic 

 and Connecticut rivers. Its shores contain ex- 



LONGITUDE, lon'jitude. If you were to 

 travel directly north from wherever you now 

 are, and a second person fifty miles east of you 

 and a third fifty miles west of you were also 

 to travel north, your paths would all meet 

 at the north pole. Each would have followed 

 a line of longitude, which is a north and south 

 line along the earth's surface. The earth may

cellent harbors. Large numbers of vessels 

 navigate its waters, for it is a convenient "in- 

 side" route from New York to Providence and 

 Boston. In the beautiful suburban villages 

 which line its shores are homes of thousands of 

 men whose business interests are in New York

 clubs, golf links and clubhouses. On the Long 

 Island shore there are valuable oyster beds and 

 fisheries, and large areas are devoted to market 

 gardening. On the Connecticut side are lo-

be thought of as a huge ball divided into 360 

 north-and-south sections, the lines between the 

 sections being the meridians, or principal lines 

 of longitude. Of course the earth has no real 

 meridians, so for convenience most nations 

 agree upon an imaginary meridian running 

 through Greenwich observatory, near Lond< 

 as the principal meridian, with others at in 

 vals of %(jo part of the way around the worl 



A degree of longitude is the distance bet 

 a point on any meridian and the point di 

 east or west on the next meridian. New Yor 

 which is shown by the map to be 74 

 longitude, is therefore 74 meridians f: 

 Greenwich. A comparison with the ball w 

 make it plain that the space between two me- 

 ridians is greatest at the equator, and becomes 

 smaller as the poles are neared. Thus it is 

 that at New Orleans a degree of longitude is 

 about sixty miles, while at Winnipeg it is 

 than forty-five miles.
