AQUATIC PLANTS.

there is the expense of pots, and labour of necessary 

 shifting. The sides of the tank are raised above the 

 ground-level, but for the sake of appearance we 

 should prefer such a tank to be sunk in the ground. 



It admits of no doubt, that where possible this 

 class of plants, like every other, should be grown in 

 the natural style, with room for root-development. 

 A very fine effect may be produced, and we have 

 seen nothing to equal the arrangement in the garden 

 belonging to Mr. T. D. Hoey, of Nevny. He has a 

 large pond, generally oblong, but of irregular out- 

 line, inio which 

 there is a con- 

 stant and large 

 supply of clear 

 water. All 

 around there is 

 every condition 

 from mountain 

 side to marsh, 

 and the varied 

 vegetation so 

 skilfully placed 

 renders this 

 glen a garden 

 paradise. For- 

 tunately a large 

 quantity of 

 stone has been 

 available, and it 

 has beenusedall 

 around where 

 "water touches, 

 so that there is 

 no trouble with 

 the washing or 

 settling down of 

 soil, which hap- 

 pens more or less when there is no support. Eockwork 

 has been carried up in various directions in order to 

 avoid a monotonous level, and good spaces have been 

 .provided for large colonies of choice kinds just at the 

 level that sustains the requisite amount of moisture. 

 A path encircles this pond and its boggy sides, while 

 against the slopes of the glen, on the other side of 

 "the path, more rockwork is continued, furnishing 

 ^lendid sites for Bamboos, choice Coniferse, and 

 fine-flowering climbers, such as the Ayrshire Eose 

 and Clematis. In the pond are several small islets, 

 and one of these with Spircea Ulmaria jl. pi. in 

 flower was very fine indeed. A large Heath bed is 

 one of the features, and among the Heather many 

 choice plants flourish on account of the protection 

 it affords. Many plants commonly grown on the 

 ordinary border, were here particularly fine with an 

 extra amount of moisture: such were Folygonum 



Sieboldi, Hetnerocallis fulva, and Funkia Fortunei. 

 Although this aquatic and bog garden is wonder- 

 fully interesting and complete, still further extension 

 of culture has been made in another part of the 

 establishment, and with the introduction of a new 

 plan. In a low part of the garden is a pond, and in 

 it islands have been formed, and peninsulas have 

 been thrown out, of soil perhaps a foot above the 

 water, for the culture of Iris Eampferi, Gunnera, 

 and various other ornamental bog plants. In this 

 case, the soU is confined by piles of moderate- 

 sized tree-stems 

 which are 

 driven into the 

 mud of the 

 pond. This ob- 

 viates the use 

 of stone. 



In the Cam- 

 bridge Botanic 

 Garden is an 

 arrangement 

 which avoids 

 entirely the use 

 of pots, costs 

 little in con- 

 struction, and 

 is at the same 

 time natural in 

 effect. It has 

 been found to 

 require but lit- 

 tle attention,.as 

 the majority 

 when once 

 planted take 

 care of them- 

 selves. Once in 

 the spring the pond and mounds are thoroughly 

 cleaned and set in order, and afterwards an occa- 

 sional weeding only is necessary. Plants are put in 

 at almost any time except during vriuter. There 

 is a pond of water sixty-four feet long, averaging 

 twenty feet in width and two feet deep in the centre. 

 Around the pond is a belt of grass, kept short for 

 ■walking upon. In the pond are two mounds of soil, 

 reaching to nearly the top of the water, made espe- 

 cially for Fontederia eordata and its variety angmti- 

 folia. Against the sides of the pond are moimds of 

 soil, some of peat, others of loam, from nine to ten 

 feet long, and from two to four feet wide, with a 

 height above the water of from six to nine inches. 

 Between the ends of the mounds, the slopes down 

 from the edge give depths of about one foot of water, 

 easily within reach, which are very convenient for 

 planting small submerged aquatics, and young speci- 



Aponogeton distachtoh.
