INTRODUCTION Because of the rapid increase in knowledge about precious stones on the part of the buying public, it has become necessary for the gem merchant and his clerks and salesmen to know at least as much about the subject of gemology as their better informed customers are likely to know. In many recent articles in trade papers, attention has been called to this need, and to the provision which... more...

PREPARATORY CONSIDERATIONS. I deem it unnecessary to prove that mankind stood in need of a revelation because I have met with no serious person who thinks that, even under the Christian revelation, we have too much light, or any degree of assurance which is superfluous. I desire, moreover, that in judging of Christianity, it may be remembered that the question lies between this religion and none: for,... more...

What is America? I have never managed to lose my old conviction that travel narrows the mind. At least a man must make a double effort of moral humility and imaginative energy to prevent it from narrowing his mind.

Every year adds to the number of men who feel as a friend of mine, a successful lawyer in a great city, felt when in talking of the future of his four little children he said, "For the two boys it is not so serious, but I lie down at night afraid to die and leave my daughters only a bank account." Year by year,... more...

THE RUBBER. 1. The rubber is the best of three games. If the first two games are won by the same players, the third game is played; should the score of the third game lap, a fourth game is played. 2. A game consists of five points. Should a player order up, assist, adopt, or make the trump, and he and his partner take five tricks, they score two; three or four tricks, they score one. If they fail to... more...

INTRODUCTORY Carpentry is the oldest of the arts, and it has been said that the knowledge necessary to make a good carpenter fits one for almost any trade or occupation requiring the use of tools. The hatchet, the saw, and the plane are the three primal implements of the carpenter. The value is in knowing how to use them. The institution of Manual Training Schools everywhere is but a tardy recognition... more...

KINDS OF FLIES FOUND IN HOUSES. Several species of flies are found commonly in houses. Some of them so closely resemble the true house fly that it requires very careful observation to distinguish them from it. One of these is the biting stable fly (fig. 1). It occurs frequently in houses and differs from the house fly in the important particular that its mouth parts are formed for piercing the skin.... more...
