A tale is told of a man who, having been long and hopelessly in prison, finally tried the door of his cell, and, finding it unlatched, went out to freedom. A similar revelation has come to a few single taxers. Multitudes since the time of Henry George have believed in single tax, and have represented their belief by somewhat hopelessly agitating for legislation. But during all this period the way was open to achieve the same end without it. This way has been followed by a few persons, and the six resulting areas in which single tax exists shine like minute white stars against the darker background. Some one once said to Charles Lamb, "There is a spot upon your coat, Mr. Lamb," "Clean spot, you mean," rejoined he. These clean spots, as being enclosed by the huge system from which they have freed themselves (each in its own degree), are called "enclaves," and are described in the following pages. In the area comprehended by the United States, including Alaska, Hawaii, and Puerto Rico, the five enclaves represent a proportion of 224 parts in a hundred million; in Andorra, 5000 parts in a hundred million. Are these enclaves worthy of being expanded? Are they worthy of being multiplied? This book is offered as part of the evidence. Fiske Warren Tahanto, 1921
