VI SITING A FISH HATCHERY.

and therefore I publish them in 

 The Guide to Nature for the benefit 

 of other naturalists. 



The view of the grounds with the 

 main building in the back ground 

 shows very nicely. Several very in- 

 teresting specimens of the lotus were 

 in bloom in the tubs shown at the 

 right in the illustration. 



I attempted to take some photo- 

 graphs of the fish feeding. The assis- 

 tant very kindly brought forth a pile of 

 fine chopped meat, and tossed bits into 

 the water in the place where I could 

 best set the focus of my camera. It 

 was very interesting to watch them 

 when he rapped on the pan as one 

 might do to call chickens. They evi- 

 dently knew wholly by sight that there 

 was food in the dish for them. It was 

 impossible to get a photograph giving 

 any detail of the individual fish. It 

 was a wonder to me that they did not 

 kill each other and perhaps they did 

 inflict injury upon a few, for I noticed 

 here and there after the feeding, two 

 or three floating back downwards, but 

 the keeper informed me that they 

 would ''come to" a little later, that 

 thev were probably only momentarily 

 stunned. 



In addition to this scries of pools 

 in the open ground near the main 

 buiidincf there was a series in a most 



picturesque location farther up the 

 stream. These were covered with wire 

 netting, lifting up by a cord and pulley 

 arrangement so as to balance in any 

 position. These coverings were to pre- 

 vent the deprivations by the king- 

 fishers.
