•28 A MANUAL 



make a can of this sort, from the description and the 

 engraving, at a very moderate cost.* 



Of course a simpler and more economical plan 

 would be to buy a glass or earthenware jar, fit a large 

 cork, and place it in a small basket to reduce the 

 chances of breakage, or even to invest in a small 

 tin can (though this is liable to corrosion, and will 

 not benefit your captives), but the advantage of car- 

 rying a number of bottles or jars is very great. 

 There are many varieties of sea-anemones of a very 

 small size and of delicate structure ; these should 

 have a receptacle for themselves, or they will be 

 injured by the large heavy kinds, who, in addition 

 to their own bulk, invest themselves with a coat, not 

 of mail, but of stones and shells, which lacerates 

 everything it touches — so, too, a very choice specimen 

 can be carried home by himself, and the naturalist 

 is not tormented by fears and apprehensions of what 

 will become of his treasure in that solitary jar of 

 "mixed pickles" which he dangles at his side. 

 I have seen and heard of " vascula" made of wicker- 

 work containing divers bottles and the requisite tools 

 for extraction, but I consider them to be inferior to 

 that which I have described, in consequence of their 

 greater size and unwieldiness. 



The rear-guard of our arni}^ is coming down tlie 

 hill, he represents the corps of sappers and miners, 



* The weight of the can and its contents when empt}- is three 

 pounds and a half, and its cost about six shillings.
