REGENT DISCOVERIES.

Improvement in Coloring Carpets. According to new method with tapestry carpets, as explained in a pense with the "scraping" process and to overcome in a great degree the difficulty of printing the dark shades. That is, instead of printing all the pile yarn, as hitherto practiced, the yarn is dyed to the predominating light shade or ground color, while the other colors are printed on to the dyed yarn upon the drum in the ordi- nary manner, the looped pile fabric being woven in the loom in the usual way By this means, not only is a perfectly even light ground pro duced in a printed tapestry carpet, but as the predomilat1ng light shade is dyed, not printed, the objectionable results in printing the dark colors are entirely overcome. Again, in the production of carpets involving the printing of the piece subsequent to process of weaving, the worsted yarn is also dyed to the predOminating light shade or ground color, and after ward the piece is woven in the ordi- nary manner, so that when it leaves the loom it has the appearance of a fabric dyed to one uniform color cor responding to the ground color of the carpet; upon this dyed ground are then printed the various other colors of the pattern, in this way an abso- lutely uniform shade of color for the ground being secured-a thing prac- tically impossible when the looped yarn or pile was in the gray" and where the light ground color of the pattern had to be printed by hand blocks or otherwise In either of these cases, the improved process pro- duceS much more durable coIors and much richer and more brilliant ef- fleets, while it secures that great de- s1deratum, viz, an even and unvary- ing ground color for printed tapestry carpets.
 Combination of Building materials. Considerable advantage is being claimed, especially in respect to cost and strength, in behalf of the plan Of expanded metal construction" as It is termed. In carrying out this method, sheet of metal, steel of any thickness up to cne-fourth of an inch, and any length or width, say six feet wide, is put into the expand ! ing machine; it is there punched through with rows of sits covering the whole surface of the sheet, with width of untouched steel between each line of slits of quarter or half an inch, each slit being separated lengthwise from the next slit on the line by perhaps an inch of steel The machine then stretches the slitted steel sidewise, to some six times it's original width, and when it leaves the machine it presents, roughly speaking a six-foot square piece of steel net work, with diamond shaped meshes. i The idea is that the use of expanded metal in this form, when combined with concrete, adds to the strength of the latter from seven to nine times that originally possessed another point being that such construction

 Tiles for Roof1ing.-The new plan devised in Germany for flooring, the tile roof as it is named, is declared
 by architects in that country to rep.
 resent what will be the roof of the
 future, such material and its facing
 being at once simple, cheap, and ye
 so durable, that, when once fixed, il
 will never wear out. Thus, when al
 order is given for one or more of these
 roofs, the builder, instead of ordering
 a number of the tiles, as is done il
 other cases, involving large transpor
