 crocodile, and follows her up and destroys her eggs, and now and again dedicates itself to its hate, and goes down her throat, and then spreads out its spiny fins and kills her.

The fish I know personally are interesting in quieter ways. As for instance the strange electrical fish, which sometimes have sufficient power to kill a duck and which are much given to congregating in sunken boats, causing much trouble when the boat has to be floated again, because the natives won't go near them, to bail her out.

Then there is that deeply trying creature the Ning Ning fish, who, when you are in some rivers in fresh water and want to have a quiet night's rest, just as you have tucked in your mosquito bar carefully and successfully, comes alongside and serenades you, until you have to get up and throw things at it with a prophetic feeling, amply supported by subsequent experience, that hordes of mosquitos are busily ensconcing themselves inside your mosquito bar. What makes the Ning Ning—it is called after its idiotic song—so maddening is that it never seems to be where you have thrown the things at it. You could swear it was close to the bow of the canoe when you shied that empty soda- water bottle or that ball of your precious indiarubber at it, but instantly comes "ning, ning, ning" from the stern of the canoe. It is a ventriloquist or goes about in shoals, I do not know which, for the latter and easier explanation seems debarred by their not singing in chorus; the performance is undoubtedly a solo; any one experienced in this fish soon finds out that it is not driven away or destroyed by an artillery of missiles, but merely lies low until its victim has got under his mosquito curtain, and resettled his mosquito palaver,—and then back it comes with its "ning ning."
