planted there as could be procured, and the collection has since received severaladditions from time to time. The best collections of old trees in the imme-diate neighbourhood of London, now (1837) existing, are those at Kew andSyon; but the most complete collection, where the plants are of a consider-able size, in England, and doubtless in the world, is that in the pinetum atDropmore, near Windsor, commenced by the late Lord Grenville, about 18)0,and now (1837) amounting to above 100 kinds. This fine collection is keptup with the greatest care by Lady Grenville, and every new species or variety isadded, as soon as it can be procured. All the sorts of Abietinm that are inthe country are in the garden of the London Horticultural Society; but theplants there are, for the most part, of small size.

Pinetums, by which are to be understood collections of thedbietinas plantedbv themselves, and without the intermixture of broad-leaved trees, have, sincethe commencement of that at Dropmore, been formed by several landed pro-prietors in different parts of the country; stimulated, no doubt, by the ex-traordinary beauty and interest of the Dropmore pinetum, and by the numberof new and beautiful species of pines and firs which have been introducedfrom California and the Himalayas. Many persons have also made collectionsof the dbietinaa, and planted them in ornamental grounds along with broad-leaved trees. In England, pinetums, or collections, have been made by J. T.Brooks, Esq., at Flitwick House, in Bedfordshire, where there are 100 sorts;by Sir Charles Monck, at Belsay in Northumberland; by Sir Charles Lemon, atCarclew in Cornwall; by William Harrison, Esq., at Cheshunt; by the Dukeof Devonshire, at Chatsworth ; by the Duke of Bedford, at Woburn Abbey ;by W. A. Baker, Esq., at Bayfordbury, in Hertfordshire; by F. Perkins,Esq., Chipstead Place, Kent; by Lord Arundel, at Wardour Castle ; by theEarl of Caernarvon, at Highclere ; by William Wells, Esq., at Redleaf; and byseveral others. In Scotland, the first collection of Abietinte was formed atMethven Castle, on the estate of Robert Smith, Esq. by the zeal of his able andintelligent land steward, Mr. Thomas Bishop; one has been formed at Posso,in Peebleshire (a place which has long been celebrated for its trees, see page93.), which it is believed contains a greater number of species than any otherin Scotland, though the plants are all young. At Haddo House, in Aberdeen-shire, the Earl of Aberdeen has formed a collection, and spares no expense inprocuring plants of all the new sorts as they are introduced. At Ballen-dalloch, Morayshire, George Macpherson Grant, Esq., commenced a pinetumin 1836, to which every new sort is added as soon as it can be procured. Thesoil and climate of Ballendalloch seem to be particularly adapted for theylbictinoe, as will appear by an account of the growth of some of the trees there,which we shall give in a future page; so that we have no doubt of this pinetumbecoming in a few years one of the very first in Scotland. Collections of more orless extent have also been forified at Lowhill, in Fifeshire, the property of C.Craigie Halkett, Esq.; at Hopetoun House, near Edinburgh, the seat of theEarl of Hopetoun, where there is the largest tree of A'bies Smithidna inBritain ; at Oxenford Castle, Edinburghshire, the seat of Sir John DalrympleM‘Gill; and at Melville House, Fifeshire, the seat of the Earl of Leven.For this account of the pinetums of Scotland, we are indebted to Mr. Lawson,the eminent seedsman of Edinburgh, whose communication on the subjectwill be found at length in the Gard. Mag., vol. xiii. In Ireland, the firstpinetum formed was that of the Glasnevin Garden, which was commenced in1797; and, about the same time, a number of species were planted at OrielTemple, in the county of Louth, by the late Lord Oriel. Both collectionscontinue to receive additions, Lord Viscount Ferrard, the son and successorof Lord Oriel, being, like his father, much attached to trees. In Trinity CollegeBotanic Garden, in Dublin, a pinetum was commenced in 1808; which, likethat at Glasnevin, has since received the addition of most of the new species.At Tittour, Mount Kennedy, in the county of Wicklow, a collection has beenformed, and great attention paid to the culture of the pines in it, by JohnNuttall, Esq.; and a collection has been commenced in the Belfast Botanic
