They so seriously affect our work and our success that to know them and to have them at command are of the first importance. Some of these we seek bere to collate and compare, aiming at comprehensiveness and accuracy, and hinting the lines along which investigation should be carried on, and additions constantly made.

Our Earth. --The dimensions of our globe are familiar—its circumference of about 25,000 miles, its diameter of about 8000, its surface of 200,000,000 square miles, of which three fourths represent water. Europe, inclusive of the British Isles, has an area of 3,600,000 square miles, with a coast-line of 20,000 miles ; Asia, an area of 17,000,000 quare miles, with a coast-line of 40,000 miles ; Africa, an area of 11,500,000 square miles, with a coast-line of 16,000 miles.

If, then, Australia represents the unit of measurement, Europe has a fraction more area, South America twice as much, North America more than two and a half times as much, Africa nearly four times, and Asia nearly six times as great area.
The river systems are immense. They represent a total length of over 125,000 miles, or five times the circumference of the earth. The navigable
