THE PRACTICAL GARDENER. 



frost does not seem to injure them so much as the late Frosts 

 in spring, and the occasional ones of summer, as was the case 

 in ISOD, when the frost of June, which was unusually severe, 

 just as the trees were coming into foliage. The leaves were 

 killed, and the trees pushed, late in the season, into a second 

 foliage and shoots, which were killed by an early autumn 

 frost. The trees made an eflbrt to push in the spring follow- 

 ing, but failing, finally languished and died. The seeds of 

 this species ripen more freely in this country than the last 

 species, and should be collected in October when they are ripe, 

 and sown immediately, by this mrans plants are to ])c obtained 

 in plenty ; but nurserymen seldom originate them by this 

 means, and have recourse to the process of laying, and some- 

 times by cuttings. Cuttings, if put in, in autumn, succeed 

 pretty well, and may be by the autumn following expected to 

 be sufficiently rooted for planting out into nursery-lines ; and 

 layers, laid down in autumn, will also by the autumn following 

 be sufficiently rooted to be fit to plant out in lines also. When 

 cuttings are to be made use of for j)ropagating this tree, those 

 slioots of the last season's growth which are well ripened 

 should only be made choice of, and should be from nine to 

 twelve inches in length. These, if planted in moderately rich 

 ground, will root freely, and make fine plants. 



ORNAMENTAL PINES. 



Under this head may be included a number of extremely 

 curious and interesting species of the Pinus genus, which, 

 cither from their delicate habits, diminutive growth, or other 

 circumstances, render them unfit foi planting in the general 

 plantations, and are generally admired and most in character 

 whon planted singly on the lawn, or in systematic order in the 

 arboratum, &c. So numerous and interesting is this genus, 

 that they may be said to form of themselves a very complete and 

 interesting collection, and as such have been exemplified at Drop- 

 more, the seat of Lord Grenville, where there is the finest col- 

 lection in cultivation in Europe, and contains fifty-two species, 

 including the three species Araucaria, Cufini/ig/ia?fi}a, and 

 Dam?nara, to which they are nearly allied, and which are
