The art of making hand cushion lace was soon acquired by most of the residents in the Saxon mountains, which is a poor country, as the occupation of most of the inhabitants was mining, and it frequently happened that the wages were so low, and the means of sustaining life so expensive, that some other resource had to be found to make life more bearable.  Barbara Uttmann’s invention was thus a blessing to the country, and her name is held in high esteem.  A monumental fountain is to be erected at Annaberg, and is to be surmounted by a statue of the country’s benefactress, Barbara Uttmann.  The statue, modeled by Robert Henze, is to be cast in bronze.  It represents Barbara Uttmann in the costume worn at the time of the Reformation.  She points to a piece of lace, which she has just completed, lying on the cushion, the shuttles being visible.

Some point, Valenciennes, and Guipure laces are made on a cushion by hand, with bobbins on which the thread is wound, the pins for giving the desired pattern to the lace being stuck into the cushion.  A yard of hand cushion lace has been sold in England for as much as $25,000.  The annexed cut, representing the Barbara Uttmann statue, was taken from the Illustrirte Zeitung.

A Boston paper tells of a man who built two houses side by side, one for himself and one to sell.  In the house sold he had placed a furnace against the party wall of the cellar, and from its hot air chamber he had constructed flues to heat his own domicile.  The owner of the other house found it very hard to keep his own house warm, and was astounded at the amount of coal it took to render his family comfortable, while the “other fellow” kept himself warm at his neighbor’s expense nearly a whole winter before the trick was discovered.

IMPROVEMENTS IN CONCRETE CONSTRUCTION.

Portland cement concrete if made with a non-porous aggregate is impervious to moisture, and yet at the same time, if not hydraulically compressed, will take up a sufficient quantity of moisture from the air to prevent condensation upon the surface of the walls.  It not only resists the disintegrating influences of the atmosphere, but becomes even harder with the lapse of time.  It may also be made in several different colors, and can be finished off to nearly a polished surface or can be left quite rough.  Walls built of this material may be made so hard that a nail cannot be driven into them, or they can be made sufficiently soft to become a fixing for joinery, and, if a non-porous aggregate be used, no damp course is required.  Further than this, if land be bought upon which there is sufficient gravel, or even clay that can be burnt, the greatest portion of the building material may be obtained in excavating for the cellar; and in seaside localities, if the (salt) shingle from
