In order to make the gables of the cabin the 

 ends of horizontal cross-pieces, or poles, are 

 secured to each pair of uprights, 3^ ft. 

 from the ground. The tops of the saplings 

 are then brought together so as to form 

 two arches, one for each end of the cabin. 

 The horizontal spanners are 7 ft. long. 



A ridge pole is then laid on the forks pro- 

 vided by the two arches, and side spanner 

 poles are secured to the arched poles. The 

 intersecting parts of the various saplings 

 are fixed in place by means of suitable wire 

 or twine. 



Soft wire is preferable, as it can be 

 quickly applied, twisted and secured by 

 means of pliers. Soft annealed piano wire 

 is the most serviceable. A tinned wire, 

 about 18 gage, is also good for this purpose. 

 We now have the frame ready for the parts 

 necessary to carry the tent cloth ; for it is 

 not desirable to stretch the sheet over the 

 wooden frame. We may take a lesson 

 from the umbrella frame which has light 

 ribs to support its covering. 



Wires are used to support the sheet of 

 the tent. A few suggestions as to the 

 correct way of attaching these wires may be 

 of great service to the novice. The poles 

 should have their ends cut off square with a 

 small saw. A hatchet might split the 

 wood. Several sets of wires should be 

 prepared beforehand. The end of each 

 wire should have a twisted loop to attach to 

 one end of a pole. Wire nails, 2Y2 in. long, 

 are best adapted for holding the wires. 

 These should be driven into the ends of the 

 cross and longitudinal poles, or spanners, 

 the loops affixed and the loose ends of the 

 wires attached to the other ends of the 

 respective poles. 



The main sheeting is then unrolled and 

 strung over the five taut wires, one end of 

 the sheet being secured to the lower wire, 

 which is threaded through the seam. The 

 other end of the sheet passes behind the 

 other base wire. After stretching the sheet 

 tight the surplus end is secured to the taut 

 portion. The triangular end sections are 

 then attached with safety pins, or buttons 

 or snap-fasteners may be provided for the 

 purpose. It will thus be seen that the 

 entire fabric forming the tent is suspended 

 on wires and does not come into contact 

 with any portion of the wooden frame. 



It is not necessary in a cabin tent of this 

 construction that the poles should be 

 driven into the ground. Instead, a wire 

 may be stretched across to connect the 

 lower ends of the front and rear arches.

Holding Papers on a Movable 

 Sloping Desk-Top 



IT is difficult to hold letters or other 

 pieces of paper on the surface of an 

 ordinary sloping top desk, even though 



paper weights are used for the purpose, 

 as the desk-top must be raised at times 



Brass wire clip to hold sheets of paper on a 

 sloping desk top that is raised occasionally 



to gain access to the contents within. 

 The illustration shows how a permanent 

 clip or holder can be made of a piece of 

 light brass wire and spring and placed on 

 the desk-top. A small hole sufficient to 

 take the wire size is drilled down through 

 the desk-top. It in no way interferes with 

 the opening and closing of the desk- 

 top. — F. W. Bentley. 



Keeping Oil from the V-Belt 

 of a Motorcycle 



OIL leaking through the shaft bearing 

 and running on the pulley face and 

 entering the groove caused con- 

 siderable trouble on a V-belt ste el ring or 

 drive of my motorcycle. This f 

 difficulty I easily over- 

 came by attaching a 

 steel flange to the inner 

 surface of the pulley, 

 which had a diameter 

 considerably larger than 

 that of the pulley flange. 

 This prevented the oil 

 from getting into the 

 pulley groove by caus- 

 ing it to drip from the 

 flange edge. The flange 

 was out of the way.
