"Before Rosener designed this machine it was also necessary to design tu'o others for preparing the bark so it could be used. The present machines'represent an outlay of nearly $100,000 and reveal how our company will spend money to obtain just the kind of equipment it needs to keep its manufacturing up to the highest possible efificiency.

"During the rvar the company was able to save quite a bit of money by the use of redwood bark when rags had advanced to such a high figure, but it had been able to manufacture such a supirior tyge.of roofing by the :utilization of the redwood bark that even when rags dropped lower than bark in price it continued to use the redwood.

"We have proven conclusively that bark makes roofing better. It makes the roofing more lasting', more durable because every lumberman knows that redrvood is the oldest living thing-rvhich means durability-and that redwood bark is acid-proof and fire-resistant."

Most of the redwood bark used originates in the forest of Humboldt county. Before the concern saw the value of the bark lumbermen, generally, were in a quandry as to how to dispos'e of it. While, of course, we use only a fraction of the available bark it is interesting, nevertheless, to note how this waste product has been turned to commercial use.

Lumber Consumption Figures For 1923

A survey recently compl.eted by the Los Angeles Chamber of Commerce, discloses some highly interesting facts and figures in regard the import -of-lumber pfoducts through the port of San Diego, during the year 1923. Los Angeles and vicinity used morslumber in 1923 than the whole state of New York, with enough left over in favor of Los Angeles to provide homes for a good sized clty.

Enough lumber was brought into Los Angeles Harbor dtrring 1923 to build over Two Hundred Thousand five room homes, nearly six hundred per working day. out of a total of. 2,021,336;,321 fe,et, 1,414,936,000 board feet remained in the city. Of the lumber that remained in I.os Angeles last year, most of it went into dwellings. Granting that 25 per cent was uS'ed for other purposes, there still remained 1,0ffi,976,M board feet. Thii was enough to construct 106,000 five-room bungalows, it was said.

These homes, if placed on SO-foot lots, would make a string 1000 miles long, or enough to build solid on both sides of the road all the way from Los Angeles to San Francisco.

This would be dwellings enough with an,average of four to a family to provide for a population equal to a city the size of New Orleans or Cincinnati. or the two cities of Atlanta and Albany, N. Y., combined.

There has been a tremendous increase in the import of lumber, it was revealed. The year 1921 broke the record up to that time, with 614,098,918 board leet; 1922 almost doubled this, with 1,159,475,383 board feet. Then came the greatest year of all, 1923, with 2,02I,336,321 board feet. The I92l lumber import was valued at approximately $15,000,000, while thatof last yFar ran well over $60,000,000, it was declared.
