288 YACHT EQUIPMENT 



useful size of tank is 3 x ij x ij feet high. On a 

 long cruise the contents of this can be occasionally 

 transferred to barrels and headed up ; to be sent home 

 or stored in the hold. 



Large but more delicate specimens can be stored in 

 tobacco jars with very wide mouths ; these are made 

 in various sizes, and the lid is screwed down tightly 

 on to a rubber flange by an iron clamp and thumb- 

 screw. Two 4-gallon jars of this type, racked in a 

 padded box, since they are brittle, will hold a very large 

 quantity of material. 



Sweetmeat jars, with a cork ring, and the numerous 

 forms of screw-topped jar on the market, are not to 

 be recommended for prolonged storage where they 

 cannot be constantly examined, least of all in the 

 tropics, unless packed in barrels or metal tanks, or 

 tied over with bladder. 



Stout " sample-bottles " of various sizes (4, 8, and 

 12 ounces, are useful) and stout unshouldered tubes 

 of various lengths with carefully picked and fitted 

 corks (not bungs or shives), will carry the smaller 

 stuff. Fill all tubes and bottles with fluid up 

 to the very cork. Put on the galley-range a good- 

 sized glue-pot, containing paraffin wax (melting-point 

 ioo° F., but harder if for use in the tropics) with a 

 little white beeswax, and dip necks and corks twice 

 in this to make all tight. These sample bottles are 

 best stored in trays, partitioned by corrugated straw- 

 boards ; but, for reasons of great weight, too many 

 trays should not be stored in one case. Long tubes 

 are best in a racked box. Sawdust packing is messy ; 

 it sticks to wet fingers, and is transferred unpleasantly 

 to the specimens.
