LAW AND ATONEMENT. "The soul that sinneth it shall die," and it "shall not die." The first quotation, "The soul that sinneth it shall die," is often produced in support of the scholastic idea that the law of God was inexorable, that is absolute or unconditional, not to be moved or its penalty escaped by reformation or petition. The language of the text is very definite, and,... more...

 hope, Carnes," said Dr. Bird, "that we get good fishing." "Good fishing? Will you please tell me what you are talking about?" "I am talking about fishing, old dear. Have you seen the evening paper?" "No. What's that got to do with it?" Dr. Bird tossed across the table a copy of the Washington Post folded so as to bring uppermost an item on page three. Carnes... more...

There are two causes of failure to make this crop uncertain. One is because the soil is not kept clear of weeds, and the other is that it is not properly enriched.

FARCOT'S IMPROVED WOOLF COMPOUND ENGINE. In a preceding article, we have described a ventilator which is in use at the Decazeville coal mines, and which is capable of furnishing, per second, 20 cubic meters of air whose pressure must be able to vary between 30 and 80 millimeters. In order to actuate such an apparatus, it was necessary to have a motor that was possessed of great elasticity, and... more...

LINKS IN THE HISTORY OF THE LOCOMOTIVE. It is, perhaps, more difficult to write accurate history than anything else, and this is true not only of nations, kings, politicians, or wars, but of events and things witnessed or called into existence in every-day life. In The Engineer for September 17, 1880, we did our best to place a true statement of the facts concerning the Rocket before our readers. In... more...
