POMADE 'RRIS. (From poma, a lid, and 

 derris, a skin ; the membranous covering 

 of the seed-vessel. Nat. ord., Rhamnads

Greenhouse, New Holland, evergreen shrubs ; 

 yellow-flowered, except where otherwise stated. 

 Cuttings of half-ripened shoots cut to a joint, 

 dried at the base, and inserted in sand, under a 

 glass ; peat and sandy loam. Winter temp., 38 

 to 45. Elli'ptica, with the exception of having 

 creamy-like flowers, resembles the Ceano'thus 

 azu'reus, and no doubt would prove almost as 

 hardy against a wall.

PONDS are reservoirs of water dug out 

 of the soil, and made retentive by pud- 

 dling with clay their bottoms and sides. 

 Puddling is necessary in almost all in- 

 stances, and the mode of proceeding is 

 thus detailed by Mr. Marnock, in the 

 United Gardeners' Journal. When the 

 excavation is formed, or partially so, the 

 bottom puddle near the outer edge is 

 formed, and upon this is raised the up- 

 right or side puddle ; and as this proceeds, 

 the ordinary clay or earth is raised at 

 the same time, by which means the up- 

 right puddle is retained in its place ; and 

 ultimately the sides, being formed in a 

 sloping direction, admit of being covered 

 with gravel or sand, and may be walked 

 upon, or stakes may be driven to a con- 

 siderable depth without reaching the 

 puddle, or in any way injuring it. This 

 can never be the case if the puddle, as is 

 sometimes done, be laid upon the sloping 

 side of the pond. The sides may slope 

 rapidly, or the reverse. If the slope be 

 considerable, sand or gravel, to give a 

 clean appearance, will be more likely to 

 be retained upon the facing ; plants car 

 be more easily fixed and cultivated ; gold- 

 fish, also, find in these shallow, gravellj 

 parts under the leaves of the plants suit- 

 able places to deposit their spawn, and 

 without this they are seldom found tc 

 breed. Ponds made in this way may be 

 of any convenient size, from a couple oi 

 yards upwards to as many acres. The 

 following is the section of a pond thus 

 formed ;
