“Now, I shall endeavor to give you a description of the exterior of the ‘big-house,’” said Mr. Midith, as he began to draw a neat outline, on which he located four “big-houses” and a cross-section of a community, as shown on page 115. “Before I give you a detailed description of the different parts of this outline, I shall have to refer you to the diagram I drew for you the other evening. (Page 58.) You will there notice that our communities are all numbered, as Community 1, 2, etc. Hence, a country as large as the United States, containing nearly 3,500,000 square miles, divided up into communities like ours, containing about four townships, or 144 square miles each, will make about 25,000 communities. I told you, in brief, that the ‘big-houses’ are situated along the motor-lines, on the perimeter of the communities, and are about half mile apart, as indicated by the dots in Community No. 1 (page 58). The ‘big-houses’ of each community are also numbered, as indicated by the figures 1, 2, 3, etc., in Community No. 1 (page 58). “It is not strictly true that the ‘big-houses’ are located a half-mile apart, for about every four miles or closer, as indicated by the square dots in Community 2 (page 58), we have a large warehouse or factory instead of a ‘big-house;’ but these warehouses, etc., are very similar in structure to a ‘big-house.’ Now, we want to bear in mind that the communities are numbered, so that when we know the number of a certain community we know in what particular part of the country it is situated; and we also want to remember that the ‘big-houses’ of each community are numbered consecutively from 1 to about 135, including the warehouses, factories, etc. The number of a ‘big-house’ also indicates its location in the community. “From what I have already said, then, you have learned the following facts: “1. Our countries, or grand divisions of land, are divided into rectangular communities, about 24 miles long and 6 miles wide. 2. Each community is surrounded by 60 miles of motor-line. 3. Railroads are about 100 miles apart, running both north and south and east and west. 4. Each community under ordinary conditions contains about one hundred and twenty ‘big-houses.’ 5. The inmates of each ‘big-house’ generally number about one thousand. 6. The inhabitants of each community, then, are nearly one hundred and twenty thousand. 7. Each community has about fifteen or twenty warehouses, mills and factories. 8. Both the communities and the ‘big-houses’ are numbered. [Illustration: This diagram represents a cross-section, somewhat more than half mile wide, and extending across from the motor-line to the field. A is a park one-fourth mile wide, extending from the motor-line to the boulevard all around the community. 1 represents a double track motor-line. 2, 3, 4 and 5 represent “big-houses.” 6 represents a hundred-foot wide boulevard. 7 and 8 represent foot-paths.
