THE YOUNG JSTATtTKALIST. 



you will learn how to treat him by referring 

 to page 134 of the Y. N. 



There is another large kind of water beetle 

 (Hy.ird.is piscas), which may be placed in the 

 aquarium with safety, it is larger, and the 

 antenna? are shorter, but it nevertheless is 

 quite harmless, being a vegetarian. Those 

 little beetles that are whirling about on the 

 surface may be bottled if you like, but they 

 will fly away some night if the aquarium is 

 not covered up. Get a stick and poke in 

 among the weed, out comes something that 

 is sailing along in a series of jerks, fish him 

 out, and you will see that this is the water- 

 boatman (Notonccta), and a very interesting 

 object it will prove. Next turn your attention 

 to the small fish that you see very lively in 

 the bottom of the pond. These are stickle- 

 backs, and if you take any of them home 

 they must be kept in a separate glass, as they 

 are very pugnacious, although very interest- 

 ing on account of their building nests (see 

 Y. N., page 29). 



Now get the weed hook, and throw it in 

 among the weed, pull it out again, when it 

 brings a lot of weed along with it, do this 

 several times, and then examine the weed 

 well ; a lot of small animals of different sorts 

 will be found among it, and some of the weed 

 can also be taken at the same time. 



Now let us make the best of our way to the 

 nearest brook. Here we shall find some 

 fish of another and a still smaller kind, they 

 are Minnows, they go in companies, and, you 

 must be very cautious in inserting the net 

 into the water, otherwise they will all be off. 

 Gently bring it underneath where they are, 

 and then strike upward. These will be the 

 most lively little animals you will have, and 

 now I think we have got very nearly all our 

 bottles filled, and time is getting on. But 

 before we return let us just look along this 

 stream for some Caddis Worms, they are 

 larvae which construct cases of all shapes, 

 made up of bits of stick and stone, &c, which 

 serves to protect them from their enemies. 

 You will only be able to keep them a certain 



; time, for they will turn into flies with trans- 

 ! parent wings, and will fly away, 



• This completes our afternoon's work, every- 

 ; thing cannot be done at once, so we have only 

 been able to procure a few of the many kinds 

 of animals that are procurable for our pur- 

 ] pose ; various seasons and different localities 

 j will furnish a variety of sorts, and it is the 

 I same with your aquarium as it was when 

 j Rome was built, you cannot do all in one 

 day. 



HOW TO BEGIN. 



SUPPLEMENTARY REMARKS ON 

 SETTING. 



By Barnard Lockykr. 



May I venture to supplement the remarks 

 ! that have lately appeared in the pages of 

 j your periodical as to setting ? I am not 

 certain that Dr. Knaggs has not already 

 given much the same directions as those I am 

 j about to offer, but at any rate they appear to 

 i have been overlooked by your correspon- 

 dents. The directions given all mention 

 ; running a pin through the wings, a plan 

 ! wh : ch, as Mr. Clifton remarks, is liable 

 (unless very great pains be taken) to leave its 

 j mark behind in the shape of an unsightly 

 hole. And this in very delicate geometrse, 

 &c. (such as Scotosia dubitata) frequently 

 elongates into a slit, thus spoiling the speci- 

 | men. My plan entirely obviates the necessity 

 for running this risk. It is thus carried out. 

 Procure the following implements. Firstly, 

 I several small squares of cork. Into two of 

 these run a long pin (one into each) so that 

 the point projects very little below the cork. 

 : Then run a hole through the centre of the 

 ' cork a little on one side of the pin, and nearly 

 at right angles with it, but slightly slanting 

 downwards. Now having procured several 

 long elastic pigs bristles (these may be had at 

 butchers I believe) run one of them through 

 ; this second hole. This completes No. 1, 

 I thus—
