SUPPOSE that a habit of minute observation of nature is one of the most difficult things to acquire, as it is one which is less generally pursued than any other study. In almost all departments of learning and investigation there have been numberless works published to illustrate them, and text books would fill the shelves of a large library. Thoreau in his “Walden” has shown an extremely fine and... more...

CHAPTER I A. BACKGROUND After viewing the destruction wrought by the eruption of Mt. St. Helens in Washington State in May 1980, President Carter became concerned about the impacts of a similar event of low probability but high damage potential, namely a catastrophic earthquake in California, and the state of readiness to cope with the impacts of such an event. As a result of the President's... more...

If our readers have perchance stumbled upon a novel called "The Improvisatore" by one Hans Christian Andersen, a Dane by birth, they have probably regarded it in the light merely of a foreign importation to assist in supplying the enormous annual consumption of our circulating libraries, which devour books as fast as our mills do raw cotton;—with some difference, perhaps, in the result, for... more...

RENAISSANCE PANELS FROM PERUGIA. The carved walnut panels from the choir stalls of the Church of San Pietro de' Casinense in Perugia, designed by Stefano da Bergamo in 1535, which are given as illustrations in this number, are excellent examples of the ornament of the later period of the Italian Renaissance. This form of ornament was first used in flat painted panels upon pilasters, such as the... more...

STEAM ENGINE VALVES. By THOMAS HAWLEY. In considering the slide valve in its simple form with or without lap, we find there are certain limitations to its use as a valve that would give the best results. The limitation of most importance is that its construction will not allow of the proper cut off to obtain all the benefits of expansion without hindering the perfect action of the valve in other... more...

COCOS PYNAERTI. This is an acquisition to the dwarf growing palms, and a graceful table plant. It first appeared in the nurseries of M. Pynaert, Ghent, and is evidently a form of C. Weddelliana, having similar character, though, as shown by the accompanying illustration, it is quite distinct. The leaves are gracefully arched, the pinnules rather broader than in the type, more closely arranged, and of a... more...

"TRY, TRY AGAIN." T is a true story that I am going to tell you now. It is about a little boy whose name was William Ross. Having had a present of a pencil, he thought he would make use of it by trying to draw.His first attempts were poor enough.

FOUNDATIONS IN QUICKSAND. Foundations in quicksand often have to be built in places where least expected, and sometimes the writer has been able to conveniently span the vein with an arch and avoid trouble; but where it cannot be conveniently arched over, it will be necessary to sheath pile for a trench and lay in broad sections of concrete until the space is crossed, the sheath piling being drawn and... more...

THE NEW LABOR EXCHANGE AT PARIS. NEW LABOR EXCHANGE, PARIS. There will soon be inaugurated (probably about the 14th of July) a new establishment that has long been demanded by the laboring population, that is to say, a new labor exchange, the buildings of which, situated on Chateau d'Eau Street, are to succeed the provisional exchange installed in the vicinity of Le Louvre Street. The new... more...
