quantity and remOTing double the saw kerf. I think that Belgium condi- 

 tions are fast coming to exist in America and that we will have to apply 

 their methods. And the experiments which we have made in the use of 

 the band resaw have shown all this can practically be done with profit 

 and with practically no change in your present equipment other than 

 to substitute lighter blades in your sawmill and a somewhat slower feed 

 while the saw is actually In the cut, to install a resaw (to make up for 

 the falling off in the capacity of the band mill) to make at least every 

 alternate cut as compared with the band mill, to resaw blade taking out 

 but one-half of the sawdust that you are ail of you removing now with 

 the band mill. 



The difiiculty which one has to encounter in advocating the use of the 

 thin blade is largely due to the fact that sawmill men do not know the 

 tensile strength of baud saw blades turned out by the leading manufac- 

 turers. The strength of these saws in the braze, namely, the weakest 

 part of the saw, is 140,000 pounds per square inch. Take a 14-gauge, 

 12-inch saw ; each strand represents practically a square inch of cross 

 section. Thus the descending strand and ascending strand would repre- 

 sent two square inches. The breaking strain of such a blade Is this, 

 that if the strain were evenly distributed it would be 280,000 pounds. If 

 you allow yourself a factor of safety of twenty, you could safely carry 

 a strain of 14,000 pounds on such a blade. I think it may safely be said 

 that none of you are carrying a strain of over two-thirds this amount. 

 Now, if you would decrease the thickness of your saw blade one-third and 

 retain your present strain you would do as good work certainly, as you 

 would not require as much strain to take out 3/32 Inches of saw kerf 

 as you would to talie out plump %-lnch saw kerf. This would be on the 

 same principle that it does not take as much power to make a %-inch 

 chisel cut a %-Inch mortise as it does to cause a %-inch chisel to cut a 

 %-inch mortise. The sawmill men are growing more and more to appre- 

 ciate the resaw to increase the capacity of the mill. 



On the Pacific coast they have standardized the mill, making a posi- 

 tion for the resaw alongside of the sorting chains, placing jump rolls in 

 the sorting chains by which the inspector can send any stock that he 

 wishes to resaw by means of driven rolls, transfer chains, etc. The resaw 

 feeds the material back again on the sorting chains, when it again passes 

 to the jump rolls and may be returned for resawing a second or third 

 time, as desired. In other words, they have this matter solved very 

 nicely on the coast, making it a simple operation to install a resaw 

 actually outside of the mill proper in a position adjacent to the front 

 end of the sorting table, so that any stock which is sent from the sorting 

 table to the resaw is returned to the table at the front end thereof and 

 in such a position that it cin be disposed of as seems best, to either 

 resaw a second time or otherwise. 



Here in the East where the timber is small it is often desirable to 

 install the resaw in the sawmill in front of the edger, as by so doing a 

 saving can be effected in edging. A 2-Inch plank with wain and bark 

 thereon when made into two 1-Inch boards will yield one board much 

 wider than the other. This extra width is just so much gained. This 

 installation has become standard in the East, and to anyone interested 

 we would be pleased to send blueprints showing details. 



The capacity of a resaw may be judged from a report given at one time 

 by the Cary-Halliday Company of Memphis wherein It stated that one of 

 our resaws with a 19-gauge saw resawed 39,000 feet of lxl2-lnch or 

 lxl3-lnch, I forget which, cottonwood in nine hours. 



I understand that what your association is most interested in is the 

 capabilities of the band resaw used under various conditions, and in 

 this paper I have attempted to give some ideas along this line. This 

 question of sawing wood is an old one. I suppose the prehistoric men did 

 more or less sawing, using a fish bone. This was probably an Interesting 

 subject in those days and it is an Interesting one still. I find some 

 new problems popping up every day, questions to be solved, conditions 

 to be met, so that even in this old and hackneyed subject draftsmen 

 are employed daily getting out new and improved machines and tools to 

 meet your various requirements. 



I fear that in going into this subject I have not proven as Interesting 

 as I should. There is an old saying from which one might infer that 

 "sawing wood and talkativeness do not go together," and perhaps that 

 accounts for this rambling talk. I trust, however, that it has not been 

 entirely uninteresting, and I assure you that It any of you have any 

 problems to solve which are in my line I will be very glad to take the 

 matter up personally with you. Thank you for your Indulgence. 



Southern Logging Superintendents' Association 

 "You can bet that from this time on I am going to know just exactly 

 what everything costs me," said a logging superintendent to his employer 

 on his return from the meeting of the Southern Logging Superintendents' 

 -Association, which was organized on September 23 and 26, 1910. as a 

 result of a movement started by the Lumber Trade Journal of New 

 Orleans. 



The object of this association is to cut down the cost of logging opera- 

 tions by discussion of problems in logging that have been solved by the 

 men who are doing the talking. The men who attend are taught by their 

 fellowmen to work from the standpoint of their employers rather than 

 their own. They learn how to cut down costs, as well as new methods of 

 doing certain work that is less expensive than the methods some of them 

 may be using. 



The logging superintendent is isolated from the men who are doing 



the same work. He does not have opportunities to find out how others 

 are operating, and his education is limited to pointers that he received 

 from men who have worked in other camps. Some mill owners send their 

 men out to visit camps of other concerns, finding it to pay for the ex- 

 penditures. Every superintendent cannot spare the time to make these 

 visits, yet he could get away for two or three days to attend a meeting 

 where problems are thrashed out. 



In order to have a practical working plan the association has printed 

 a form for a monthly report of logging operations, made up from forms 

 in use by various members. These blanks will be furnished to all who 

 will ask for them. The second month of their use will show their value, 

 and each month will give a basis for comparison that will have a tend- 

 ency to cut down costs. The different items on these blanks will be dis- 

 cussed at the next annual meeting of the association. 



Here are some reasons why each of you should have your logging 

 superintendent join the association : 



First. The logging superintendent, each year, is spending In the United 

 States alone $150,000,000 in getting logs to the mill. This is too much 

 money to be spent by men having no combined system. 



Second. Because logs have gotten to be the most expensive part of the 

 lumber business on account of the short line railroads having to be built 

 so far away from the trunk lines where a number of the mills are located. 



Third. Because conservation of the forests is a matter that Is before 

 the public at the present time, and the logging superintendents will have 

 this question to battle with in the near future. 



Fourth. Because improved machinery and systematic methods among 

 the manufacturers have reduced the cost from pond to car as low as pos- 

 sible, and, owing to the present condition of the lumber market, we most 

 turn our efforts to another department of the business to accomplish 

 what we should realize in the way of dividends. 



Fifth. Because the logging superintendent and his crew are forced to 

 stay in the woods and swamps, where in a great many cases they are 

 supplying the logging camps with brawn instead of brains. 



Sixth. Because he needs the aid of every other superintendent to help 

 him improve his labor, to make It more loyal, and to adjust camp equip- 

 ment and location so as to tempt the immigration of a higher class of 

 labor to run the logging end of the lumber business. 



Seventh. Because the equipment of the logging superintendent Is gen- 

 erally all portable and live stock, which takes a great deal of money to 

 buy, and on account of this condition it takes close attention and really 

 more intelligent care than the manufacturing machinery, which Is sta- 

 tionary. 



Eighth. Because conditions, timber, soil, elevation of land and weather 

 will compel him sometimes to make decisive plans without his having 

 time to consult his manager. Therefore the experiences of the fellow 

 that has had the same troubles and conquered them successfully that he 

 heard at the meeting will be of great benefit. 



Ninth. Because there are only a few logging superintendents that are 

 furnished with and keep detailed cost sheets, showing what he is actually 

 doing in each department. Some do not know what their logs cost them 

 as a whole. 



Tenth. Because the meetings held by the manufacturers and lumber 

 newspapers very seldom discuss the logging end of the business, which is, 

 as stated, one of the most expensive, and a department on which every 

 other Interest of the business must depend entirely. 



Eleventh. Because there are a great many lumber concerns that make 

 only a small success and some a failure on account of the logs and 

 timber not being properly cared for, and costing too much. 



Twelfth. Because its uniform cost forms will create competition among 

 the superintendents and department foremen of the different plants, 

 which is the life of all enterprises. 



Thirteenth. It will give the man in charge of the logging department 

 the best excuse In the world that he can offer to his manager for a few 

 days' vacation, where he can get away from the scent of overworked 

 cattle, mules, etc. ; where he can mix, mingle and rub up against the 

 outside world and drink In the exhilarating air of the city, which will 

 make him shave up, clean up, straighten up his head ; which will revive 

 his step to such an extent that he will believe that he is several years 

 younger; it will put him in line with some of the other department heads 

 who enjoy this privilege and which has helped them to perfect their 

 present system and intelligent ways and means of arriving at a low cost 

 sheet. 



Last, but not least, the cost is small, only $5. There are no salaries, 

 and no expenses other than for stationery and postage, and there will 

 be no dues as long as there Is enough balance la the treasury to carry 

 these charges. 



The association is growing — it will do a great work for all owners of 

 timber lands. Send in the name of your superintendent, for It will benefit 

 you manyfoid. 



Value to Be Gained From Association Standpoint 



Those to whom the proceedings are of the most Interest are busy men : 

 attendance at the association takes time ; upon most of the superintend- 

 ents it entails considerable expense and, to those who do attend, do the 

 benefits justify the expenditure incurred? That some profit Is expected Is 

 indicated by the success of the gatherings, and the evidence of those who 

 make it a point to be present would prove conclusively that something Is 

 gained. 



The benefits derived from attending the conventions will not always
