contact witli the heated wick tube and enclosure, and is then 

 caused by the cap to impinge against the fiame, tlius ensuring 

 perfect combustion and a very brilliant, steady, and practically 

 smokeless flame. The bottom of the lamp is formed with per- 

 forations for the entrance of the air, and perforations are likewise 

 made in part of the base-plate surrounding the enclosing tube 

 of the burner. 



A NEW BAG CLIP. 

 Messes. John Soutiigate & Soks, of 75 and 76, Watling-street, 

 London, have invented a new clip for the well-known " Gladstone " 

 and other bags, designed to take the strain off the centre of the 

 lock by holding the ends of the bag together. The originally- 

 designed clip, wliich consisted of a metallic disc at each side, which 

 was turned down so as to tighten upon the bag, was always untrust- 

 worthy, because it Avould work loose at any time ; and then, again, 

 anybody could easily and quickly undo it. An improvement on 

 that was a sliding clip catching a hasp like that of a lock inside. 

 This hasp constituted one of its defects, as also its liability to work 

 loose, so as not to keep its place at all when tilted up. Messrs. 

 Southgate & Sons, have now invented a clip which is claimed 

 to be an improvement on anything else of the kind. It 

 consists of a hinge on one side of the bag, which catches 

 by pressure over a metallic catch or fastening on the other 

 side, and to be undone requires the two sides of the bag 

 to be pressed tightly between the finger and the thumb. It 

 acts exactly like a spring-latch, one spring being in the upper part 

 of the hinged clip, which resists slightly the attempt to push it 

 down, and the other consists in the resisting power of the bag's 

 mouth itself, which is sufficient to act as a permanent spring. 



AN IMPROVED LAWN-MOWER. 

 What is claimed to be an improvement in lawn-mowing machines 

 has been invented by Mr. Thomas Knowles, of Turtin, near Bolton, 

 in the county of Lancaster. The inventor says, in effect, that his 

 invention is designed to produce a machine capable of cutting 

 grass growing at the edges of lawns, or even the grass in borders 

 or verges. To effect this purpose revolWng blades, acting in con- 

 junction with fixed knives, are placed on opposite sides of the 

 frame of the machine. To ,this frame are secured bearings sup- 

 porting an axle rotating therein, and carrying rollers at the ends. 

 This shaft or bearing is connected with suitable gearing, or chain 

 and gearing combined, so that motion can be iransmitted from the 

 axle carrying the rollers to the shafts on which the knives are 

 mounted. The machine is propelled in the usual way by a handle. 

 The rollers rotating the knives are placed in such a position that 

 the blades operate on the grass to be cut previously to the drums 

 pressing on the grass, and this, the inventor claims, gives facility 

 for cutting grass on edges and narrow borders.

ANSWERS TO CORRESPONDENTS. 



■f*^ Please address Chess Editor. 



M. Strong. — A pawn can only be taken en passant immediately 

 after moving two squares, not afterwards. Although we can put 

 eight Queens on the board without checking each other, we do not 

 know the rule by which it is done. Perhaps some of our readers 

 may know. 



H. W. Sherrard. — Problem received with thanks. With your 

 kind permission we shall make use of it somewhere else, as no sui- 

 mates are to appear in Knowledge.
