The four seasons are noticeable generally in 

 the temperate zones, but in the torrid zone 

 there is usually only a wet and a dry season. 

 The polar regions, too, have only two seasons, 

 winter and summer. Ordinarily in the northern 

 hemisphere the months of March, April and 

 May are called the spring months; June, July 

 and August, the summer; September, October 

 and November, the autumn; and December, 

 January and February, the winter months. In 

 the southern hemisphere the seasons are re- 

 versed, spring beginning in September, sum- 

 mer in December, autumn in March and winter 

 in June.

SEA SQUIRTS, skivurts, or ASCIDIANS, 



asid'ianz, a group of mollusks of a low order, 

 so called because they have the habit of squirt- 

 ing out jets of water when irritated. The 

 young of these animals resemble the tadpole of 



a frog and are free-swimming; the adults have 

 leathery, bottle-shaped bodies and remain 

 through life attached to stones, shells, wharves

and other fixed objects. The mature form is 

 simpler in structure than the tadpole. 



A par-t of Seattle's water front 



BATTLE, seat "I, WASH., the largest 

 city of the Pacific Northwest, the county seat 

 of King County and one of the. most important 

 seaports on the Pacific coast of America, is 

 situated on the east shore of Puget Sound, 864 

 miles by water north of San Francisco and 185 

 miles by rail north of Portland, Ore. The 

 Canadian boundary is 125 miles to the north. 



General Description. Seattle occupies a 

 beautiful site, with the snow-capped Olympic 

 Mountains and Puget Sound on the west and 

 Lake Washington and the Cascade Range on. 

 the east. Lake Washington, twenty-two miles 

 long and four miles wide, is connected with 

 Puget Sound by a ship canal over eight miles 



long. The canal passes through Lake Union, in 

 the north-central part of the city, and connects 

 with the Sound by means of a large lock, made 

 necessary by the difference in levels between 

 the bodies of salt and fresh water. The com- 

 pletion of this canal greatly extended the city's 

 water front. The site is hilly, and some parts 

 of the city have an altitude of 500 feet. Many 

 streets extending east and west traverse steep 

 slopes, but by means of cable cars the inhabit- 

 ants travel them with ease. In three localities 

 where these elevations offered the greatest ob- 

 stacles to the city's progress they were removed. 

 Jackson Street was lowered 124 feet below its 

 highest point; Denny Hill was lowered 130 feet,
