The kodak was the natural outcome of the roll film system. The first one appeared in 1888, and its development, which proceeded simultaneously with the film discoveries, soon reached the point where the loading and unloading could be done in daylight. Daylight developing soon followed, and the dark room, as far as the kodaker was concerned, took its proper place as a relic of the dark ages.

With 1914 came autographic photography, so that now with a kodak in one pocket and a handful of film in the other, the amateur is equipped for a picture-making tour of the world--not simply a pictorial record, but a written record as well, for autographic photography permits the dating and titling of each negative directly after exposure.

How Deep is the Deepest Part of the Ocean?

The Wonder Book of Knowledge — Part 106

Man has not been able to tell definitely just what the greatest depth of the ocean is, because it would be a practically unending task to go over every bit of it to take measurements. A great many exploring expeditions have been sent out to determine that interesting information so far as possible, however, and one of these, the Murray-Challenger expedition, has reported that the greatest depth that could be found in the Atlantic Ocean is 27,366 feet, in the Pacific Ocean 30,000 feet, in the Indian Ocean 18,582 feet, in the Southern Ocean 25,200 feet and in the Arctic Ocean 9,000 feet. They also stated that the Atlantic Ocean has an area in square miles, of 24,536,000; the Pacific Ocean, 50,309,000; the Indian Ocean, 17,084,000; the Southern Ocean, 30,592,000 and the Arctic Ocean, 4,781,000.

The use of the expression “get the sack,” when we mean “to be discharged,” originated through the impression made upon people in this country when stories were brought to them of the way the Sultan of Turkey disposed of members of his harem of whom he had tired. When he wanted to get rid of one of his harem he was said to have had her put into a sack and thrown into the Bosporus. People who heard of this report repeated it to others and they became so used to telling the tale that they slipped quite naturally into the habit of saying “to get the sack” when they meant that they expected to be put out of a position suddenly.
