have been received for the " Arboretum Britannicum.^'' 29 



number of places celebrated for their trees are omitted. We 

 should be greatly obliged to such persons if they would write 

 to the gardener at such places on our behalf; or inform us of 

 the name of the place, and that of its proprietor or gardener, 

 in order that we may send Return Papers thither ourselves. 



Our readers will bear in mind, that we wish to know the height, 

 and number of years planted, of all foreign trees whatever that 

 have been more than ten years standing in any one place; and 

 the^ height, and circumference of the trunk, at a foot from the 

 ground, of all indigenous trees in any way remarkable for their 

 age, height, breadth, or rapidity of growth. 



It would be of great use to us to know the height and girt, at 

 a foot from the ground, of the largest oak, ash, elm, sycamore, 

 &c., in the grounds or park of every country seat throughout 

 Great Britain and Ireland ; with the kind of soil and subsoil on 

 which the trees stand; their exposure, and their probable age. 

 Surely, it cannot give much trouble to any gardener or forester 

 to send us this information. The height may be taken by a 

 practical man, with sufficient accuracy for our purpose, by the 

 eye; and the circumference of the trunk at a foot from the 

 ground, by passing a string round it, and sending us the length 

 of the string; or if this be too much trouble, the diameter of the 

 trunk may be estimated by the eye, as well as the height of the tree. 



As we find that we shall be able, by publishing double numbers, 

 to finish the Arboretum on the 1st of June next, whatever in- 

 formation may be sent to us (and we shall be glad of hints on 

 propagation, culture, uses, the formation of plantations, fences, 

 &c., because our object is to produce a complete Encyclojxjedia of 

 Arboricidture) should be received by the 1st of March. In the 

 Gard. Mag. for April a supplementary list to this now given will 

 be published ; and, when the Arboretum, or rather Encyclopedia^ 

 is finished, both lists will be incorporated into one, and the name 

 of the proprietor, and (where it is known) that also of the gar- 

 dener or forester who prepared the list, will be added, and the 

 whole published, in a tabular form, in that work. 



We may take this opportunity of mentioning that, through the 

 kindness of a wealthy and distinguished individual, who volun- 

 teered to have a number of full-grown trees drawn for us at his 

 own expense, we are enabled to render the work far more com- 

 plete than we at first contemplated ; by giving, in addition to the 

 portraits of trees of ten years' growth, to the scale of a quarter 

 of an inch to a foot, portraits of full-grown trees of one or more 

 species of all the principal genera. These full-grown trees are 

 drawn to a scale of a quarter of an inch to 3 ft. ; and, as a spe- 

 cimen of them we give Pav/« flava. {fig- 2.) Fig. 3. is a tree of 

 ten years' growth, of the mountain ash (Morbus aucuparia), to 

 a scale of a quarter of an inch to a foot. The botanical speci- 

 mens at the foot of both trees are to the scale of 2 in. to a foot.
