of glue, unless otherwise recommended by the glue manufacturer. 

 It will then be melted in a water bath and applied to the wood 

 at a temperature of about 60 degrees Cent. (140 degrees Fahr. )■ 

 After gluing, the test blocks will be held in clamps and allowed 

 to stand for six additional days. They will then be finished, so 

 that the blocks when ready to test will have a glued joint two 

 inches square. When tested no block shall fail under a load of 

 less than 2,200 pounds per square inch, and the average shearing 

 strength shall be at least 2.400 pounds. 



Jelly Strength and Viscosity 



Jelly strength. — The jelly strength will be determined upon 

 a mixture containing twelve parts of water to one part of glue. 

 The glue will be soaked and melted as described under "Adhe- 

 siveness," then allowed to stand overnight in a refrigerator at a 

 temperature of 5 to 10 degrees Cent. (40 to 50 degrees Fahr.). 

 The relative strength of the standard sample and the manufac- 

 turer's sample will then be determined by pressure with the 

 finger immediately after the samples are removed from the 

 refrigerator. 



Viscosity. — The viscosity will be determined as in an Engler 

 viscosimeter, upon a sample containing one part of glue to five 

 parts of water soaked and melted as described under "Adhe- 

 siveness." Two hundred cubic centimeters of the glue mixture 

 will be run through the viscosimeter at a temperature of 60 

 degrees Cent. 



Grease. — The relative amount of grease present will be deter- 

 mined by mixing dye with some of the sample remaining from 

 the visco.-ity test, painting it on unsized white paper, and observing 

 the appearance. 



Foam. — The foam will be tested on the sample used for vis- 

 cosity. The sample heated to 60 degrees Cent, will be beaten 

 for one minute with a power egg beater, or similar instrument, 

 and allowed to stand one minute or until the height of the foam 

 can be measured. 



Odor. — The odor of the glue when in the hot solution must 

 be sweet, and must remain sweet for forty-eight hours; that is, 

 free from any suggestion of deteriorating animal matter. 



Marking. — The glue which has been tested and passed shall 

 be barreled in the presence of the government's representative 

 and marked with the run number, date of run, and inspector's 

 stamp. The glue Vk^hich is marked in this manner may be sold 

 as certified glue, and its use will be permitted in airplane factories. 



Louisville Veneer Industry Expanding 



Louisville has been conspicuous as a veneer center for some 

 time and now there is a further growth of activities centering 

 there of more than passing interest. War conditions seemingly 

 have not curtailed the demand for veneer and panels. Practi- 

 cally every veneer and panel plant there is so busy that the 

 problem is to get help and get material rather than to get orders 

 for work. 



The Kentucky Veneer Works, which is one of the busiest 

 places in Louisville, has been spreading out recently and has 

 become interested in two operations down in Alabama, one at 

 Livingston, one at Stewart. 



A new firm has been organized and put in the saddle at Liv- 

 ingston know as McGehee-McCracken Veneer Co. The president 

 of this organization is A. M. McCehee; vice-president, H. M. 

 McCracken, and secretary-treasurer, F. C. McCracken. Mr. 

 McCehee is in charge of the operations at Livingston and Stewart 

 and the selling end of the business is domiciled at Louisville with 

 the Kentucky Veneer Works at 14th and Magnolia. 



The plant taken over at Livingston is that of the Sumpter 

 Manufacturing Co. and the new enterprise also includes the 

 McCehee Lumber and Veneer Company plant at Stewart, Ala. 

 It is the intention to eventually consolidate all these operations 

 at Livingston, Ala. The present equipment down there consists
