rest they differ also in the amount of 

 rain which falls, not only annually, but 

 at particular seasons they differ in 

 having much atmospheric moisture de- 

 posited in the form of rain or dew, or 

 snow, at the different periods of vegeta- 

 ble activity or rest. Now, whatever 

 these differences are, whatever the pecu- 

 liarities of a climate from which a plant 

 comes, the gardener cannot cultivate it 

 successfully unless he secures to that 

 plant those climatal differences and pe- 

 culiarities. We often see long tables of 

 the average monthly temperature of 

 places, but these are useless. They are no 

 guides to the gardener unless they show 

 the average highest and lowest tempcfa- 

 tures of each month, as well as the high- 

 est and lowest degrees the thermometer 

 is known to reach during the same 

 period. 



CLIMBERS are plants which attach 

 themselves to supporters by their natural 

 appendages, as by their tendrils, by their 

 hooks, or by other modes of attachment.

CLIXTO'NIA. (Named by the unfortu- 

 nate Douglas, after his friend De Witt 

 Clinton, Governor of the state of New 

 York. Nat. ord., a section of Lobeliads 

 [Lobeliacea3]. Linn., \Q-Monadelphia, 

 2-Pentatidria). Hardy annuals, from Co- 

 lumbia. Seeds, in well pulverised, rather 

 light soil, in April; or in a slight hotbed 

 in March, and planted out. 



C. e'leyans (elegant). 1. Blue. July. 1827. 

 pulcheflla (pretty). 1. Blue, white. Au- 

 gust. 1831. 



CLIOCO'CCA. (From kkio, to close, and 

 kokkos, a berry. Nat. ord., Flaxworts 

 [Linaceae]. Linn., b-Pentandria, 5-Pen- 

 tagynia. Allied to Linum). Hardy 

 herbaceous perennial. Seeds sown as 

 directed for Clintonia, ; and by divisions ; 

 light loam, and a little peat. 

 C. tenuiff/lia (slender-leaved). |. Purple.

CLIPPING hedges should be confined 

 to those of the commonest and hardiest 

 varieties of shrubs, as those of hawthorn 

 and privet ; for the bruising and mang- 

 ling of the branches which accompanies 

 this operation, is very injurious to ever- 

 greens, as the laurels and holly. Those 

 are always much better kept in order 

 and within bounds by the knife. In 



clipping, many of the leaves of those are 

 cut in half, and their decayed edges are 

 very unsightly. Clipping of deciduous 

 hedges is most advantageously performed 

 in the spring and early summer. A 

 multitude of shoots are then induced, 

 which secures that chief desideratum ia 

 hedges thickness and closeness of tex- 

 ture. 



CLISIOCA'MPA NETT'STRIA. The Lackey, 

 or Barred ^Tree Lackey, Moth. " The 

 eggs of this insect in winter may be de- 

 tected easily, in broad bands round the 

 twigs of our pear, apple, and other trees. 

 They are arranged with such admirable 

 art, that they seem set by the skilful 

 hands of the jeweller (see the annexed 

 drawing). Each bracelet, as the French 



gardeners call it, contains from two hun- 

 dred to three hundred eggs, fastened by 

 their ends in a series of from fifteen to 

 seventeen close spiral circles round the 

 twig. The spaces between the eggs are 

 filled up with a tenacious brown gum, 

 which protects them from inclement 

 weather, as well as from all attacks ex- 

 cept those of man. The eggs thus placed 

 look like a ring of seed-lac, and we think 

 its name may have been thence derived. 

 They are easily crushed by the gardener's 

 knife. The caterpillars, striped length- 

 wise, blue, red, and yellow, slightly 

 hairy, and with a white line down the 

 back, appear from these eggs in the April 

 or May following. They congregate 

 early in the morning, or during rain, in 

 large nests at the forks of the small 

 branches, and are then easily crushed. 

 They enter the chrysalis state at the end 

 of June, and then they are to be found 

 in cocoons, or oval webs, powdered with
