| fogs threatens to practically exterminate them unless some means are taken to 
Prevent it. The diminution of the natural supply has led to the establishment 
o frog farms, and the Commissioner goes into the details of breeding, feeding, 
“tnd rearing of frogs. One of the difficulties is the supply of living food, and 
‘ome use meat to attract flies and other insects. There is not much difficulty 
N getting them through the tadpole stage by protecting the pond from birds 
‘nd other enemies, but the critical time comes when the legs are developed, the 
lis absorbed, the gills give place to lungs, and the tadpole becomes a frog. 
Itis stated that there is a frog farm in Ontario, where the waters are simply 
} Stocked with mature frogs, and the young allowed to take their natural course;,. 
Yet some 5,000 Ib. of frog legs are produced annually. 
CANNING FRESH EGGS. — 
| dtrer many attempts, which resulted in whole or partial failure, it would 
‘Dpear that eggs have now been successfully canned. ‘The process consists of 
| °Pening the eges, separating the albumen from the yolk, and placing them 
| ““parately in the cases, in which they are then frozen. ‘Thus treated, they will 
ep perfectly fresh until wanted; and fresh eggs for confectioners’ use are 
%btainable all the year round. Many tons of frozen canned eggs are being sold 
‘0 hotelkeepers, bakers, confectioners, pastrycooks, and others in New York ;

TRAPPING DINGOES. 
Ay old trapper, interviewed by one of the staff of the Sydney Morning Herald, 
} Advises that, if a man intends to devote his time to the work, he should have at 
} “ast fifty traps, to be set at various distances, according to the area of the 
} “Ountry under his supervision and the abundance of the dogs and foxes. Before 
‘etting the traps, it is desirable that some sort of trail should be used. ‘There 
te some patent preparations to be obtained for this purpose, but the essence 
"aniseed on a piece of rag or sheepskin, drawn by a cord along the ground by 
| te party setting, is a good thing ; or portion of the offal of sheep or cattle; or 
‘ven the proverbial “red herring” will prove effective in drawing the dog or 
x to the trap. In setting the trap, sufficient soil should be scraped away to: 
illow the trap to lie in when set, so that the top of the trap is not higher than 
| the ordinary To 
€ top a piece of stiff brown paper, and carefully and lightly sprinkle it all 
°ver with the soil removed from the hole, sufficiently to cover the whole of the 
aper and trap. It is not necessary or desirable to secure the trap in any way 
| Sy chain or rope, as the dog or fox cannot go far with the trap dangling between 
his legs, and can always be tracked even if he does get away a few chains. 
Y securing the trap there is a danger of the dog jumping about in his efforts 
get loose, of dragging his leg through or breaking it off, and thus getting 
| Way. It is always better, if possible, to set the traps along or on some old 
Tack, or along a line of fence. 
Dogs seem very fond of following up old tracks, and in the case of dog- 
hoot fences they naturally run along, seeking for some place to get through. 
are should be taken not to walk round about the trap more than can be helped, 
% to leave more tracks behind than can be avoided. It is a good plan if the 
Party is on horseback to ride or lead the horse right over the spot where it is 
| ittended to place it, as the dogs will follow up the tracks of the horse and 
“variably run into the traps; also, when the trap is set and covered over the 
han should step across the trap for the same reason. If there are footmarks 
Ml round the trap, the dogs, being very cunning and suspicious, will also keep 
| 80Ing round and round; therefore, obliterate all footmarks except those going 
'tectly over the trap. The trap should be inspected twice a week, and, unless 
re off, should not be disturbed. The trapper steps right over them in going 
| “Srounds of inspection. The object should be to set them in the places most 
vel of the ground. Set the trap and lay it in this; then lay over
