APPENDIX 



laying the fish open to the chance of a great many 

 evils. 



If suitable earth is used once a week, and even 

 oftener on occasions, it can do no harm, and will 

 keep the fish safe from a great many risks besides 

 doing them very material good. I do not of course 

 mean that the usual weekly dose should be a large one, 

 as this would fill up the pond before the end of the 

 season, but that a small dose should be given generally, 

 and a large dose occasionally. I am quite sure, too, 

 that clean earth with some nice weeds growing in it, 

 looks better than gravel which is dirty. Gravel 

 shows the dirt so much, that it is almost impossible to 

 keep it looking nice where there are many fish, and it 

 also gives the water free access to any decomposing 

 matter. 



I have never come across a case of disease caused 

 by the use of earth, and should like to hear the 

 details of "C. C. C.'s" experiences with regard to 

 this matter.
