are growing ; yet thoy thrive well, and hence we may conclude 

 that a great depth of mud is not essential. There is, as a matter 

 of course, an amount of leaves which fall on the water and after 

 a time sink : these frequently blow to the sides, and are often 

 deposited in the right place to assist the plants in our case. I 

 have not had an opportunity of testing these Lilies in running 

 water, nor should I choose such a spot for them. Our lake is 

 nearly always at one level, or close upon it, with a regular supply 

 by means of a spring. The water from this source is deemed 

 " hard," but the exposure and admixture ere it reaches the plants 

 no doubt prevent any harm being done. I have an idea that 

 water strongly impregnated with lime, or that from springs on 

 the chalk, would not be so suitable ; but of this I have not so far 

 had an opportunity of making any experiments. From what I 

 observed, however, in one case the leaves were considerably 

 marked, and the flowers too, by a chalky deposit. I have only 

 so far heard of one direct or even partial failure, and that I 

 cannot explain. I am under the impression that it was owing to 

 the running water, not far from which there is, I believe, a mill ; 

 but for what purpose it is used I do not know ; it is, however, 

 possible that some floating matter may have had- deleterious 

 effects. I believe that Monsieur Latour-Marliac, to whom we are 

 greatly indebted for so many fine hybrid Water-lilies, is located 

 in a favoured spot, where springs abound from which issues forth 

 warm water. If this be so it should be a great assistance in 

 hastening on the growth from the seedling stage to the flowering 

 plant. I believe, too, that M. Marliac grows a good number in 

 tubs. This may, however, be only for the greater convenience of 

 propagation and after removal. That they may be cultivated in 

 this manner, however, in this country has been clearly demon- 

 strated at Burford Lodge, Dorking, where Sir Trevor Lawrence, 

 Bart., has a good collection under the care of Mr. Bain. I 

 believe that the tubs are protected sufficiently during the winter, 

 to prevent the water from freezing, by means of litter or leaves. 

 If not in such a natural style as one would prefer, there is at 

 least one merit in the tub culture, viz. that of an easy inspection. 

 In one garden in North Wales with which I am acquainted, viz. 

 The Plas, Tan-y-Bwlch, a start has been made by Mr. Roberts, 

 gardener to W. E. Oakeley, Esq. This has been done by forming 

 an entirely new pond for their special culture ; and as this is well
