INTRODUCTION. The origin of painting is unknown. The first important records of this art are met with in Egypt; but before the Egyptian civilization the men of the early ages probably used color in ornamentation and decoration, and they certainly scratched the outlines of men and animals upon bone and slate. Traces of this rude primitive work still remain to us on the pottery, weapons, and stone... more...

THE EDUCATION OF THE CHILD Goethe showed long ago in his Werther a clear understanding of the significance of individualistic and psychological training, an appreciation which will mark the century of the child. In this work he shows how the future power of will lies hidden in the characteristics of the child, and how along with every fault of the child an uncorrupted germ capable of producing good is... more...

INTRODUCTION The medical profession is justly conservative. Human life should not be considered as the proper material for wild experiments. Conservatism, however, is too often a welcome excuse for lazy minds, loath to adapt themselves to fast changing conditions. Remember the scornful reception which first was accorded to Freud's discoveries in the domain of the unconscious. When after years of... more...

A note to the internet reader: In the the print-on-paper edition, this chapter and the next one on vermicomposting are full of illustrations showing composting structures and accessories. These do not reproduce well on-line and are not included. Growing the majority of my family's food absorbs all of the energy I care to put into gardening. So my yard is neat but shaggy. Motivated by what I... more...

It is, in reality, the most successful avenue by which he may obtain the theory, for he learns... more...

THE LAWN: HOW TO MAKE IT AND HOW TO TAKE CARE OF IT HE owner of the average small home seldom goes to the expense of employing the professional gardener to do the work of lawn-making. Sometimes he cannot afford to do so. Sometimes skilled labor is not obtainable. The consequence is, in the majority of cases, the lawn,—or what, by courtesy, is called by that name,—is a sort of evolution which is an... more...

In vain do the inhabitants of London go to their conduits for supply unless the man who has the master-key turns the water on; and in vain do we think to quench our thirst at ordinances, unless God communicates the living water of His Spirit.—Anon. It was the custom of the Roman emperors, at their triumphal entrance, to cast new coins among the multitudes; so doth Christ, in His triumphal ascension... more...

CHAPTER 1. I AM BORN Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else, these pages must show. To begin my life with the beginning of my life, I record that I was born (as I have been informed and believe) on a Friday, at twelve o'clock at night. It was remarked that the clock began to strike, and I began to cry, simultaneously. In... more...

ELECTRICITY AND MATTER My Dear Son: You are interested in radio-telephony and want me to explain it to you. I’ll do so in the shortest and easiest way which I can devise. The explanation will be the simplest which I can give and still make it possible for you to build and operate your own set and to understand the operation of the large commercial sets to which you will listen. I’ll write you a... more...
