ENS 



A very excellent mode is to spread over 

 the surface of the bed about an inch in 

 depth of pit-sand, and covering ^ each 

 plant with a small pot made of earthen- 

 ware, painted both within and on the out- 

 side to exclude the wet that worst hin- 

 derance of blanching. To avoid this, the 

 pots should be taken off daily to allow 

 the plants to dry, and the insides of the 

 pots wiped. A sea-kale pot in minia- 

 ture, like the annexed figure, is to be 

 preferred ; and if made of zinc or other 



metal, it would be better, because not 

 porous and admissive of moisture. 



To obtain Seed. The finest and sound- 

 est plants should be selected of the last 

 plantation. For a small family three or 

 four plants of each variety will be suffi- 

 cient. Plant these in March beneath a 

 south fence, about a foot from it, and 

 eighteen inches apart. As the flower- 

 stem advances, fasten it to a 

 stake, or, if they are placed 

 beneath palings, by a string, 

 to be gathered as the seed 

 upon it ripens ; for if none are 

 gathered until the whole plant 

 is changing colour, the first 

 ripened andbest seed will have 

 scattered and be lost. Each 

 branch must be laid, as it is 

 cut, upon a cloth in the sun ; 

 and when perfectly dry, the 

 seed beaten out, cleansed, and 

 stored. 



ENGINE. This name is ap- 

 plied to many contrivances for 

 supplying water to plants. 



1. The pump-syringe, or 

 syringe-engine, can be sup- 

 plied with water from a com- 

 mon bucket, from which it 

 sucks the water through a per- 

 forated base. The handle is 

 sometimes made to work like 

 that of the common pump. 



2. The barrow watering- 

 engine is represented in the 

 next figure. It will throw 



the jet of water to a distance of forty or 

 fifty feet, or somewhat less if a rose is 



upon the end of the delivery-pipe. It 

 holds from twenty to thirty gallons of 

 water ; but may be made, with a leather- 

 hose attached, to communicate with a 

 pond or other reservoir of water. 



3. The curved barrel-engine is excel- 

 lent; for the barrel, piston-rods, &c., 

 being so constructed as to be turned on 

 a lathe, they are so accurate that there is 

 the least possible loss of power, either 

 from unnecessary friction or from an im- 

 perfect vacuum. 



ENKYA'NTHUS. (From enkuos, enlarged, 

 and anthos, a flower; the flowers swollen 

 n the middle. Nat. ord., Heathwvrts 

 [Ericaceae], Linn., I0-Decandria 1-Mo- 

 <togynia. Allied to Arbutus.) 



Greenhouse evergreen shrubs, with pink flow- 

 ers, from China. Cuttings of firm young shoots in 

 sand, under a hand-light, in April or May ; a bell- 

 glass is too close, unless a little air is admitted ; 

 sandy loam two parts, and fibry peat one part. 

 Winter temp., 40 to 45.
