Fig. 6

18. Fig. 6 shows the three Davis rollers made of rubber. One is used in the wiping out of heart growths; another for the wiping out of champs in quartered oak and other woods, which when quartered present the same peculiarities. The last has three graded sets of indentations and are used as combs for any kind of combing where rubber combs are used.

In this lesson it is not the purpose to explain the use of the tools enumerated; this will come under its proper heading when the modus operandi of graining, both by hand and by the use of other helping tools will be fully detailed.

19. Fig. 7 shows another rubber device, patented by the Ridgely Trimmer Co. The corrugations, as will be seen, are in halves and are made so that by proper pressure upon the handles curves them, enabling the operator to follow indentations, and which also produces many variations upon plain surfaces.

Fig. 9

20. Figs. 8 and 9 are handled corrugated quarter-round rubber grainers. These are especially handy in graining floors, also in getting into corners where the others cannot readily be made to fit up to the jointing of the two corners. These are also made by the above-named firm; as well as the following:

Fig. 10

21. Fig. 10 shows a rubber graining comb with graduated sized teeth, which is frequently desirable as the work shows a more natural lessening of the width of the veining from the heart outward.

22. Fig. 11 shows graduated widths steel combs in three sizes of teeth, fine, medium and coarse. These are used in plain oak combings, etc.

Fig. 11

23a. An artificial rubber thumb made from a piece of rubber about ½ an inch wide at the end, which is then bevelled to a sharp edge, and is frequently used by men who have never been able to use their natural thumb in wiping out.

23b. The check roller shown in Fig. 12 is a series of notched metal disks which are joined together. The projecting parts of the disks are brushed over with distemper color and the roller revolved over such parts of the work where the operator desires to show weather checks, which are so often seen in oak.

24. Last but not least, an abundant supply of soft cotton rags to use in connection with wiping out and in cleaning up tools.

LESSON VI.

GENERAL OPERATIONS USED IN GRAINING.

26. Graining, as it has been hinted at already, has many operations which are common to the many kinds of wood imitated, the variations being the result of the difference in their application. Therefore it is well to
