The fall-pit or tip-trap is the most extensively used, and the most constantly 
successful trap that has been tried so far, and, when constructed in a 
sufficiently large number of places, catches an immense number of rabbits. 
Well and strongly made, it will last for years, and being self-acting is always 
ready. 
The pit for the trap A BC DEF should be about 4 feet deep, 4 feet 
wide, and about 8 feet long—4 feet on either side of the fence G H, and 
should be lined with netting or logs to prevent burrowing, and also be closely 
covered with timber. eALODIS 
The flaps (of which there are two each side of the fence) should be about 
4: feet long and G inches wide, and should fit closely ; but not so as to jam. 
They should be balanced on their pivots—which may be of light iron, resting in 
auger-holesin a wooden frame—that when at rest they form a level track. 
Supported at the end away from the pit, the flap tips only when the rabbit 
arrives over the hole, and so throws it into the trap, and then falls back to 
original position. 
Flaps made of thin iron give the best results, as they are not affected by 
the weather, which causes wood to swell and warp. 
The trap should be regularly visited and cleared. If the rabbits were left 
to die-and decompose, others would be likely to avoid it.

Cautions to be Observed in Mixing and Laying. 
Any intelligent man could be taught to handle phosphorus and prepare 
phosphorised baits without carbon with safety in, twolessons. Like everything 
else, however, this requires judgment and care. If the phosphorus is dissolved 
without the carbon, the person doing so should keep to windward of the fumes 
while preparing the baits; if he does happen to inhale a little, it will not hurt 
him. They should be prepared in the open air. 
The risk in using the phosphorus in this way is slight, but, lest ordinary 
care is not bestowed, the following detailed directions are here given, which 
will apply where phosphorus is dissolved without carbon, whatever the medium 
may be which is used :— 
Take two 3-gallon buckets, and before commencing to prepare the mixture 
see that they are quite clean. Then have a supply of cold water within reach ; 
put the proper quantity of water (say 1 gallon in one of the buckets, and 5 
gallon in the other). Start the fire, and place the pollard or grain and phos- 
phorus ready to hand. Put the buckets on the fire, and as the water in the 
bucket with 1 gallon boils take it off the fire, break as directed, and put the 
phosphorus in the water, and stir quickly. At that temperature the 
phosphorus, with constant quick stirring, will be disseminated throughout the:
