 A recent issueuef the New York Her ala is printed on paper made from
 woods which have not been used here tofore for news print paper.
 The sheet which newspaper readers hold in their hands each day is made of wood If one looks closely the lit tie wood hbers can be seen, especially in the margins where printing does not obscure them. The larger part of the wood so used is ground up, while some of it is reduced by the ac- ton of chemicals. The chemical pulp proportion of 1t Is added to the ground wood to give the finished paper the required toughness.
 Spruce, abundant in the New Eng land and Lake states and in Canada, has heretofore been the standard wood as long as there was a supply sum- cient to meet the needs of the paper industry there was no reason to seek substitutes. But heavy inroads have fbeen made on the spruce forests. On rough estimate, newspaper with an average circulation of 50, GOO copies and an average edition of 20 pages, uses each day the product of about four acres of forest When this fig ure is multiplied by the great num- Der of newspapers published in the United States, many of them with much larger editions, and when this is further multiplied by 1885,, because many papers are issued every day of the year, it can be seen that the drain upon the forests is enormous. Forest CTS say that even under the most approved methods known to their pro- fession, it could scarcely be expected that spruce would be able to hold it's own, but would need supplementing by other material
 It is but natural, therefore. that pa  sources of supply which will furnish an abundance of wood pulp, at a. price which will not be prohibitive. Pop lar and few other woods are used, but they do not go very far.
 In the national forests there are lumb bermen. Yet they are available for purchase at low rates and many of the timber stands are readily ac- cessible. The forest service, in it's desire to utilize to the best advantage all of the resources of the federal timber holdings, has been seeking proper uses for these trees and has lexperimented in making pulp from them at it's pulp laboratory at Wau- sau Wisconsin. The Wausau labor atory is equipped with standard ma chinery and all experiments are car ried out under conditions which dupli- cate commercial practice
 As a final test of the value of some of these new woods under practical conditions, arran gements were made between the forest service and the Herald to print some part of it's edi- ton on paper made from various woods that showed promise as sub- stitutes for spruce. These woods were
 ground at the Wausau laboratory: the product was then mixed with the usual proportion of chemical pulp and made into news print paper rolls of which were sent to New York for the ex- perrin run.
 The new woods must fulfil many con- ditions as to color, finish and strength.
 In these trial runs, most of the paper | is made from various western frs, (which show considerable promise, but the investigators do not consider their tests complete until they have sub- jected the paper to actual printing conditions They grow throughout the mountain ranges of the wests par lticularly in the Pacific coast states. In addition to their interest in fnd- ling new uses for Httle-rsed woods, fed eral forest officers naturally desire to keep the newsprint paper manufactur- ling industry within the United States They therefore seek to present the Iopportunity offered by many of the there is a supply of cheap wood avail I able for many years to come.
 l Other woods have been tried for pulp by the forest products laboratory and other newspapers will make ex- perimental runs of the paper. Any l one interested in this experiment., ol l in other wood pulp tests carried or
