ing the egg is hatched; and then the j racy. A species never degenerates ; its 



young insect gnaws and injures the I 

 leaf, leaving a hole or scar of a burnt or 

 singed appearance. 



" Sometimes the upper surface of the 

 leaf is covered with clusters of wart- 



seed may be hybridized ; but the seed- 

 lings are not degenerate — they are 

 varieties. But varieties do degenerate: 

 Brussels sprouts grown at Malines give 

 birth to seeds that yield seedlings quite 



like substances. They seem to be oc- j degenerated ; but those seedlings, re- 

 casioned by means of a puncture made ! turned to the neighbourhood of Brussels, 



on the under surface, in which a num 

 ber of openings are discoverable, pene- 

 trating into the warts, which are hollow 

 and villous within." 



For these the only remedy is to re- 

 move the insects with the least possible 

 delay; and, if the injury is extensive, 

 adding water and liquid manure to the 

 roots rather more freely, to promote a 

 fresh and larger development of the 

 leaves. 



Deformities of the stems of trees and 

 shrubs arise from another cause — from 

 the extension of the woody fibre being 

 greater and longer continued on one 

 side, it frequently becomes contorted. 

 Gardeners usually endeavour to remedy 

 this by making an incision on the inner 

 side of the curvature, and then employ- 

 ing force to restore it to a rectilinear 

 form, causing a gaping wound, and 

 mostly failing to attain the object. If 

 the incision be made on the outer side 

 of the curve, thus dividing the woody 



yield, after two or three generations, 

 plants that arc true Brussels sprouts. 



Many varieties of wheat, excellent 

 when cultivated in one locality, yield 

 seed that produces a different and in- 

 ferior sample in another locality, differ- 

 ing in soil and annual meteorological 

 phenomena. 



DELIMA. Two species. Stove ever- 

 green climbers. Cuttings. Loam, peat, 

 and sand.

 three species, and many varieties. —

 sion or seed. Common soil. 



DENDROBIUM. Fifty-seven species. 

 Stove epiphytes. Division. Turfy peat. 



DEXDROMECON rigidum. Half- 

 hardy evergreen shrub. Seed. Com- 

 mon soil.

 moist shaded soil. 



DESIGN. " Consult the genius of 



fibres that continue to elongate most the place" before you determine upon 



rapidly, the branch or stem, with but 

 slight assistance, will recover its due 

 form, and there will be no open wound. 

 " From the fact that there is invari- 

 ably more woody matter deposited on 

 the side of a stem or branch which is 

 most exposed to the air and light, gar- 

 deners have explained to them why 



your design, is sound advice ; for 

 gardening, as in all the line arts, nothing 

 is pleasing that is inappropriate. Mr. 

 Whateley, our best authority on such 

 subjects, truly says, — 



" A plain simple field, unadorned 

 but with the common rural appendages, 

 is an agreeable opening ; but if it is 



those sides of their trained trees which \ extremely small, neithera haystack, nor 



are nearest the wall ripen, as they term 

 it, most slowly, and are benefitted by 

 being loosened from the wall so soon as 

 they are relieved from their fruit. 



" If they require any demonstration 

 that this explanation is correct, they 



a cottage, nor a stile, nor a path, nor 

 much less all of them together, will 

 give it an air of reality. A harbour, on 

 an artificial lake, is but a conceit ; it 

 raises no idea of refuge or security, for 

 the lake docs not suggest an idea of 



need only examine the trees in clumps danger : it is detached from the large 



and avenues: their external sides w 

 be found to enlarge much more rapidly 

 than their internal or most shaded 

 sides." — Principles of Gard. 



DEGENERATE. A plant is said to 

 have degenerated, or to be not of true 



body of water, and yet is in itself but a 

 poor inconsiderable basin, vainly affect- 

 ing to mimic the majesty of the sea. 



" When imitative characters in gar- 

 dening are egregiously defective in any 

 material circumstance, the truth of the 



stock, when it arises from seed without' others exposes and aggravates the fail- 

 the good characteristics of the parent, ure. But the art of gardening aspires 

 III cultivation may render a plant of [ to more than imitation ; it can create 

 altered stature, and its produce of defi- i original characters, and give expres- 

 cient flavour; but this is not degene- sions to the several scenes superior to
