ueuDeraUely will remain intact for an Indefinite time. Whatever may be either added to or elimi- mated from the pulp, its property of elas- ticity remains.
 Stones hurled against window panes made of it do no harm. Wherever the translucent pulp product is used light flows in abundantly, and there is no need of protecting iron bars. To be sure those within cannot see the outer world, for as yet the material has not been made trans parent, but that slight disadvantage is more than compensated for by the abun- dance of soft, pleasant light and its freedom from liability to break. Small boys whose delight it is to shatter windows and to throw mischievous stones may deplore the new departure, but aside from them it comes as q real boon to the busy world.
 The process of making is complicated. Various chemicals are required, and the material undergoes many changes before it becomes a substitute for glass, but a8 none of the materials used is costly this last product of the spruce retains the cheapnesl that makes all of the pulp pro- auctions of such vast service to mankind. Hhe stock can hc sawed to any sizo and shape, and each panc can either bc nailed in place or set in with putty or glue. As it is extremely light in weight the frame work docs not require to be so heavy, in addition to which advantage the cost of freightage is greatly reduced.
 Use of the Refuse.
 But of all tho discoveries which have led to the exaltation of the spruce the re- cent ones as to the utilization of waste Gp- peal most keenly to the economic mind Heretofore, and indeed at the present time, 75 per cent of the entire field is left as waste in tho slab pile and the saw;iust heap.
 The latest scientific investigations go to show that from this enormous proportion marketable materials can be produced. One of the leading French engineers has just made discovery by which the whole of the wood can be converted into gas. The apparatus for so doing is claimed to be both simple and cheap, so that without great expense it can be placed convenient to sawmills and forests. As yet the dis covcry has not been put to practical use.
 Vast quantities of starch are also con tained in this 75 per cent of waste, and it is said that once tho experiments for free ing 1t arc complete that industry alone should be worth nearly if not quite as much as tho pulp.
 To the layman it seems that before long the tree can be made to supply all human needs, except that of food, and in spite of the local feeling of assurance that our forests can be trusted to reproduce themselves the locker on can but wonder how long the supply will equal the demand and marvel that InOro care is not taken to preserve a l growth of such immense and such inCrcSs- 1 ing valuc.
 | At present t he one usc to which the spruce | pulp is put which in any way countcrbal- | anccs the immense demand upon forest land is the making of telegraph poles. They are rapidly hupplanting the tall trees that hitherto haze been deemed essential and so ill some Gcgrcc compensate for the i general devastation of spruce land. The poles of paper havo many merits. They are light in weight, they can be molded any height, and, as they arc hollow, wires can be entered with ease, in addition to all of which they arc far moro durable than the natural wood.
