In order to make this investigation as com- 

 plete and effeetive as possible. I should greatly 

 appreciate hearing from any of your readers 

 regarding their linowlcdge of any attempts 

 which have been made to use wood waste, giv- 

 ing when possible : 



a. Where the attempt was or is b^'ins made ; 



b. What products were manufactured ;

The Weight of Hickory Logs 



Louisvii^LE, Ky.^ August 2. — Editor Hard- 

 wood ItECOBD : We would be glad if you will let 

 us know tl\Q approximate weight per square 

 foot luider Scribn-u'-Doyle measurement on 

 hickory logs exported from mills in northern 

 and central Louisiana. 



C. C. Mengel & Bko. Co., 



J. C. Wickliffe, Secretary. 

 The writer has been advised that it is the 

 impression of the editor that the weight of 

 green hickory logs is approximately ten thou- 

 sand pounds per thousand feet. Both the 

 writer of the letter and the Record will es- 

 teem it a favor if anyone who has specific 

 data on this subject will communicate with 

 this office. — Editor. 



Economy in Odd Length Trimming 



In 1909 the National Lumber Manufacturers' 

 Association adopted resolutions favoring the 

 manufacture of odd lengths in flooring, ceiling, 

 siding, finish, partition and moulding. About 

 this time the Hardwood Manufacturers' Associa- 

 tion of the I'nited States and the National Hard- 

 wood Lumber Association amended their inspec- 

 tion rules and admitted 15 p?r c?nt of odd leugth 

 lumber into standard lengths. The loading lum- 

 ber manufacturers of the I'acific coast have recog- 

 nized the economy incident to the production of 

 odd length stock, and while heretofore they have 

 cut their lengths into multiples of two feet, they 

 now trim to odd feet where economy can be 

 effected. 



Statistics gathered on the Pacific coast and In 

 the yellow pine regions in the South show that 

 the manufacture of only even lengths results in 

 a waste of material, and that a considerable 

 saving can be effected by cutting odd len.gths. 

 L'nder the conditions that prevail on the Pacific 

 coast the making of odd lengths will increase the 

 different classes of products by nearly 3 per cent, 

 and thus a saving will come from material that 

 was heretofore wasted. Statistics gathered in the 

 yellow pine "region covering both short leaf and 

 long leaf yellow pine show that a saving of 

 about 2 per cent was effected as the average of 

 six mills that employ this system. In hardwood 

 lumber manufacture the saving is consideralily 

 greater, and in one instance at least a poplar 

 manufacturing conce?^ reports that since it 

 adopted the odd length system it fluds that it is 

 effecting an economy of nearly 17 per cent. By 

 reason of splits and defective butt logs it is un- 

 deniably true that the economy in producing odd 

 lengths from hardwoods is much greater than it 

 is in soft woods. 



The Forest Service has recently issued a cir- 

 cular showing that the percentage in odd lengths 

 in ordinary construction is much greater than any 

 possible percentage that could be obtained where 

 even au odd length trimming system prevails. 

 Some buyers employ 40 per cent of odd lengths, 

 but others use as little as 5 per cent. In hard- 

 woods it is reasonable to assume f i-om the informa- 

 tion at hand that the odd length system of trim- 

 ramg would make a saving of fully 10 per cent 

 in lumber output, and this constitutes a remark- 

 ably high percentage of profit, as in hardwood 

 lumber production the odd length trimming will 

 probably be employed in at least a majority of 

 the saw mills. The grading rules of the two 

 hardwood associations named admit 15 per cent 

 01 odd lengths to standard grades, but it is doubt- 

 ful if as large a percentage as that could ever be 

 attained in general hardwood production. 



The ordinary gang trimmer, of either overhead 

 or underhung construction, cannot readily 'ue 

 adapted to odd length trimming. It therefore has 

 remained for the progressive saw mill machinery 

 manufacturing house, the M. Garland Company 

 of Bay Cit.v, Mich., to put on the market a new 

 and high-class type of odd length trimmer which 

 meets all the requirements of saw mills cutting 

 as high as 12,000 feet an hour. One of these 

 machines built by the M. Garland Company is in 

 operation by that progressive lumber manufactur- 

 ing house, the Yellow Poplar Lumber Company of 

 Coal Grove, O., and this company alleges that the 

 machine is effecting an economy of $65 a day. 



The accompanying illustration shows the 

 simple and compact type of odd-length trimmer 

 produced by the M. Garland Company. This 

 machine will cut from 8 to 20 feet, even or odd 

 lengths, with only three saws, while the old style 

 of edger required nine saws. This machine does 



away with a large proportion of belt and saw 

 troubles. 



Referring to the letters on the engraving, "B" 

 represents the skids where the lumber starts ; 

 saw "C" cuts off one end and when the board 

 teaches rolls "D" it starts in the direction of 

 the arrow toward bumpers "E." These bumpers 

 are one foot apart and are operated by foot 

 treadles "F." The bumper stops the board at 

 the desired point while still being carried toward 

 the next saw. "H" is a tilt saw which may be 

 raised or left down as desired, and the untrimmed 

 end of the board cut by saw "G." "I" shows a 

 tlutch gear to start and stop the feed chains. 



The M. Garland Company reports that It has 

 built thousands of trimmers of the E and G and 

 two-saw type, some of them to cut odd lengths, 

 but believes that this is the king pin trimmer of 

 them all. This is the first time this machine 

 has ever been illustrated and will prove of espe- 

 cial interest to hardwood manufacturers, as its 

 elBciency and economy has been fully tried out. 



Lumber manufacturing methods have been no- 

 toriously wasteful for years, and if this new trim- 

 mer will effect an economy of even 5 per cent on 

 the 50,000,000,000 feet of lumber produced in the 

 TTnited States annuail.v it will be equivalent to 

 adding 2,500,000.000 feet to the annual output. 

 The utilization of the odd-length trimmer is the 

 taking of a practical step in forest conservation. 



For Hoo-Hoo 'Vifitors to San Francisco. 



The unrivaled climatic and scenic features of 

 California in general and of the country adjacent 

 to San Francisco in particular, need no special 

 comment before the general public. The Hoo-Hoo 

 officials have been indeed wise in selecting such 

 a spot for the coming general assembly to take 

 place in early September. 



Ira P. Rowley, general Hoo-Hoo secretary, has 

 issued a statement from the San Francisco head- 

 quarters, with a view to bringing before the 

 visitors the various points of interest which are 

 worthy of mention and should be seen during the 

 slay in that city. The various structures of note, 

 such as the Appraisers building, Fisherman's 

 wharf. Fort Mason, and the magnificent new post- 

 oiBce are described in detail. 



A point of more than usual interest is Fort 

 Winfield Scott, a relic of the days when law and 

 order were maintained in California only by the 

 use of military patrol. The fort stands at th« • 

 entrance of Golden Gate and is still garrisoned 

 by a few soldiers and equipped with the old-style 

 gun. 



Another point of historic interest is Ports- 

 mouth square. Here the first American flag was 

 laised in this territory in 1848. This tract con- 

 tained the first custom house, and it is said that 

 during the famous gold rush a hotel was built 

 on it for $30,000, which rented for $15,000 a 

 month. It was here that Robert L. Stevenson 

 spent a great deal of his time.
