THE NEW RUBBERSET NAIL BRUSH, 



A Rubbcrset Sanitary Nail Brush, as illustrated below, is the 

 latest achievement of the makers of the famous Rubberset shav- 

 ing, tooth and paint brushes. The bristles of this brush are stiff 

 and thick, specially selected so that they will not soften from 

 usage or constant immersion in water, and each tuft of bristles 

 is firmly gripped in its 

 hard rubber base, elimi- 

 nating all possibility of 

 the individual bristles 

 becoming loose. An- 

 other feature of this i ; 

 nail brush is that the 

 handle is made of hard 



wood and water-proofed, so dial ii may even be subjected to 

 boiling water without danger of injury to either base or bristles.

A RUBBER BLOWER FOR ANTISEPTIC POWDER. 



A preparation now on the market for the relief of sufferers 

 from colds, catarrh, hay fever, influenza, bronchitis and all kin- 

 dred and similar maladies, depends largely for its success on a 

 rubber bulb or powder blower. The preparation 

 consists of an antiseptic powder composed of min- 

 eral salts, to be used in sterilization of the mucous 

 membrane of the nose and post-nasal cavity. This 

 is effected by means of 

 the rubber blower, in the 

 manner illustrated. The 

 rubber bulb is pressed 

 llat. the tip inserted in 

 the powder and the pressure suddenly 

 released, when it will be found that a 

 quantity of the powder has been 

 sucked up into the bulb. The blower 

 is held at a little distance below the 

 face and tlie powder, a thin cloud of which is made by pressing 

 the bulb sharply in quick succession, is inhaled. Then in a simi- 

 lar manner the powder should be inhaled through the mouth and 

 exhaled through the nose. [Maignen Chemical Company, 1311

THE •COMPACT ■ PNEUMATIC CAMP BED, 



The cut below shows the Whall Compact Pneumatic Camp 

 Bed, an accessory which especially commends itself to the 

 camper because of its light weight (it weighs only 12 pounds) 

 and because of its imperviousness to both wind and water. The 

 outside covering is made of 12-ounce brown waterproof duck, 

 with a fullness of 68 inches over the shoulders and of 30 inches 

 at the feet, allowing ample room for hags and blankets. It 



opens at the front, almost the entire length of the bed, permit- 

 ting of airing as well as arrangement of the licdding. The air 

 sack — made of rubber stock under the company's Longitudinal 

 Stay Device patent, which confines the air in sections — is the 

 width of the bed and 48 inches long. This air sack is in a boxed 

 pocket, the bottom and sides of which are made of waterproof 

 duck to keep the moisture of the ground from reaching the air 

 sack. Tubes for inflation and valve connection are furnished 

 with each camp bed. This "Compact" bed retains many of the 



features of the better-known ''Comfort" Sleeping Bag made 

 by the same concern, but it is lighter in weight and less ex- 

 pensive. [Metropolitan Air Goods Co., Reading, Massachu-

INSULATED WIRE AND CABLES. 



An interesting lecture was lately delivered before an industrial 

 school in Boston by W. I. Middleton, electrical engineer of the 

 Simplex Wire & Cable Co., Boston, upon the manufacture and 

 testing of insulated wire and cables. His talk was more or less 

 informal, and was illustrated by slides showing the machinery 

 and apparatus used in the above operations. The entire process 

 was followed, from the tinning of the copper wire to prevent 

 any action of the free sulphur in the rubber compound on the 

 copper, to the completed aerial, underground or submarine cables. 



In dealing with the subject the manufacture of rubber com- 

 pounds was first taken up, the machinery for handling the raw 

 rubber being shown by slides at its various stages of operation, 

 the necessity being emphasized of preventing foreign substances 

 from getting into the compound and thus spoiling it as an 

 insulator. 



The lecture was likewise illustrated by a number of pictures 

 which showed among other subjects the tubing machines and 

 the large vulcanizing drums, while the process of vulcanization 

 was likewise explained. Other features described were the 

 braiders, the waterproofing and finishing of braids, and the 

 varior.s ways of laying up copper strand and multiple conductor 

 cables, as well as the lead covering process and the armoring 

 of submarine cables. 



In order to make the completed cable free from defects, the 

 rubber-covered wire should be carefully tested as it passes 

 through the various operations. The views exhibited included 

 those of the different testing sets for insulation resistance and 

 capacity, as well as the generator and transformer sets for 

 voltage tests from 500 to 110,000 volts. The large tanks neces- 

 sary for submerging great quantities of wire at the same time 

 were also represented. 



An important point urged by Mr. Middleton was the desira- 

 bility of uniform specifications on insulation, which subject had 

 lately been reported upon by the Joint Rubber Insulation Com- 

 mittee, and their report reprinted by the Simplex company. 



CENSUS STATISTICS OF COTTON GOODS PRODUCTION, 



In the issue of March last the varieties and uses of cotton 

 were dealt with, as well as the principal statistical facts affecting 

 the production, of the staple. An interesting sequel to this article 

 is the Census bulletin of textile manufactures, in which cotton 

 goods, as recorded for the census of 1909 (the latest return 

 available), hold the leading place: 



Flax, Dyeing, 

 Total. Cotton. Wool. Silk. etc. etc. 

 Textile establishments in 



United States 5,352 2,698 1,124 852 252 426 



Capital (millions of dol- 

 lars) 1,841 986 506 152 83 114

of dollars) 1.685 829 507 197 68 84 



Primary horse power. . .2,099,050 1,400.226 400,762 97,947 92,369 107,746 



Including hosiery and knit fabrics, cotton goods had thus 

 slightly over 50 per cent, of the establishments in the combined 

 textile industries, while the capital and value of products were in 

 about the same proportion. The amount of primary horse power 

 used was about 70 per cent, of the aggregate employed in the 

 textile industry generally, the larger amount of mechanical force 

 required for the operation of a cotton mill being thus indicated. 



The special statistics relating to the cotton industry show 

 that the consumption of raw material by that branch was as 

 follows :
