The opening · free to read
This text accurately reproduces the original book except for adherence to Project Gutenburg guidelines. Each project title is followed by its original page number to allow use of the alphabetical contents (index) at the end of the book. The book used very complex typesetting to conserve space. This transcription uses simple one-column linear layout.
The text only version is of limited use because of the widespread occurrence of diagrams and illustrations. Use the pdf version for the complete text.
Many projects are of contemporary interest--magic, kites and boomerangs for example. Try a "Querl" for starters.
There are many projects of purely historical interest, such as chemical photography, phonographs, and devices for coal furnaces.
Another class of projects illustrate the caviler attitude toward environment and health in 1913. These projects involve items such as gunpowder, acetylene, hydrogen, lead, mercury, sulfuric acid, nitric acid, cadmium, potassium sulfate, potassium cyanide, potassium ferrocyanide, copper sulfate, and hydrochloric acid. Several involve the construction of hazardous electrical devices. Please view these as snapshots of culture and attitude, not as suggestions for contemporary activity.
Be careful and have fun or simply read and enjoy a trip into yesterday.
