Gigantic Antartic Icebergs

"The snowfall of each year adds a new stratum to this ice cap, which is as distinguishable to the eye as is the annual accretion of a forest tree," writes Gen. A. W. Greely, U. S. A., in the Ladies' Home Jouraal. "Tfius in centuries have accumulated on antárctica these snows, which by processes of pressure, thawing and rsgelation have formed an ice cap that in places exceeds 3,000 feet in thickness. Through the action of various forces - that of tontraction and expansión by changing temperatura being, perhaps, the most potent - this ice cap creeps steadily seaward and projecte into the ocean a perpendicular front from 1,000 to 2,000 feet in height. The teraperature of the sea water being about 29 degrees, the fresh water ice remains unwasted and the ice barrier plows the ocean bed until through flotation in deep water disruption occurs and the tabular berg is formed. These bergs are of a size that long taxed the belief of men, but it is now well establiehed tb&t bergs two miles square and 1,000 feet in thiclüiess are not rare. Others are as large as thirty miles in length and soma nearly 3,000 feet in thickness, their perpendicular, sunwasted sides rising from 200 to 400 feet above the sea."
