cooling it was transparent, and nearly as tough and hard as shell lac. After many experiments, Mr. Prideaux considers that the kouri resin will be an important addition to our materials for alcoholic varnishes. It is harder and more free from colour than mastic, quite as soluble, and perhaps less than one tenth of the price. He also thinks it may by used as a gas-light. It was tried as sealing-wax, but found not to adhere to the paper. (Ibid., p. 254.)"

S."

Cupressus sempervirens. Page 2466. line 32., add: "There is also a very beautiful old cypress at Stockton House, in Wiltshire, the only relic of the old garden. It is not very tall, as the leading shoot was broken by wind and snow many years ago; and it terminates in several spires. We have no means of ascertaining its age; but it is evidently very old, and is a remarkably fine specimen. 1. 44., add, after "Mount Sion:" "A tall cypress, an American traveller informs us, is now the only tree on Mount Sinai. It stands in the centre of a valley, high up the mountain, surrounded by other mountains, one of which bears the sacred name of Horeb. The cypress was planted by the monks, more than 100 years ago: it is surrounded by a stone fence, and near it is the fountain of Elias, which the prophet is said to have dug with his own hands. (Incidents of Travel in Egypt, &c., as quoted in the Athenæum, Aug. 26.)"

2471. 1. 3., dele “for having been wounded by Francis I., who is said to have struck his sword into it, in his despair at losing the battle of Pavia," &c. The tree struck by Francis was a poplar; see p. 2589. 1. 7., add, after full stop: "In the year 1810, this remarkable cypress was struck by lightning, and left in its present shattered condition; but previously to that time it had a handsome well-proportioned head. At the height of 19 ft. from the ground it divides into six large limbs. Its roots extend to a great distance, and to such an extraordinary depth, that when a well was dug near the tree some years ago, they were found 150 ft. below the surface of the ground."

1. 27., add to the end of the paragraph: "These trees, in 1838, were in a state of rapid decay."

2475., add, before "Statistics:

"The Fungi on the cypress are: Peziza cupréssina Batsch, Cypélla Cupréssi Fr., Stachylidium scéptrum Corda. - M. J. B."

1. 32., add to "Statistics," before "In France:" "In Scotland, at Biel, in East Lothian, it is 120 years old, 41 ft. 2 in. high, and with a trunk 6 ft. 10 in. in circumference at 2 ft. from the ground."

Juniperus. 2488., add to the list of fungi : Agýrium cæ'sium Fr., Sphæria Juniperi Fr.; Hysterium tortile Schwein., on J. virginiana; Podisòma Juniperi virginianæ Fr., Urèdo Juníperi Lk.; Gymnosporangium sabìnum Fr., on savine.-M. J. B."

2505., add, at the bottom of the page:

“J. hemisphærica Presl grows above the boundary line of trees on Mount Etna, as high as 7100 ft.; as does Bérberis etnénsis Presl. (Comp. to Bot. Mag., i. 92.)"

Agave americana. 2529., add to the paragraph as follows:-"In the year 1837, a plant of this species of Agàve flowered at Clowance, in Cornwall, the seat of Sir John St. Aubyn, Bart., of which the following account has been sent to us by the gardener, Mr. T. Symons :-'This plant, of which fig. 2546. is a portrait to a scale of 1 ft. to 4 in., by Mr. Rutger, jun., is 23 ft. high. Mr. Rutger, sen., my predecessor, informs me that, when he came to Clowance, in the year 1800, he found the plant in a small tub; and that about the year 1806 he turned it out, and planted it in the flower-garden, on the site where its remains still stand. For many years, it was nearly stationary, making but little progress in point of size; which may be accounted for by no particular attention having been paid to the preparation

of soil, as the object of planting it out was rather to obtain additional room in the green-house, than any ulterior view with respect to its flowering. About ten years ago, the plant began to appear in a more thriving state; and, during the last four years, it made rapid advances towards maturity. At the latter end of last June, when the flower-stem made its first appearance, the plant was 7 ft. 2 in. high; the diameter of the trunk, at 1 ft. 8 in. from the ground was 2 ft. 3 in.; and the leaves 7 ft. 3 in. long, 13 in. wide, and from 5 in. to 6 in. thick near the base; its rapid growth during the last four years is, most likely, owing to the roots having penetrated into a subsoil more congenial to its growth than the soil in which it was planted. Allowing the plant to be about 25 years old when turned out, it may be considered as being about 56 years old when it flowered. Its site was in the flower-garden, on a border sloping to the south, backed with a fence and shrubbery as shown in the sketch, where it never had any protection, otherwise than by being screened from the north by the shrubbery behind.

"Indications of its blossoming appeared towards the latter end of June, when I perceived that the central leaves were bursting open; and, being gratified at the idea of seeing it in bloom, I was determined to particularly observe the growth of the flower-stem, and accordingly kept a daily journal of its progress. During the first 10 or 12 days, it grew from 6 in. to 7 in. in 24 hours: afterwards its daily growth gradually diminished; and, when approaching its extreme height, its progress was not more than in. during the above period: cloudy weather or a fresh breeze invariably retarded its growth. On the 1st of July, the flower-stem was 10 ft. 11 in. high, and by many it was at that time thought to resemble a gigantic asparagus. On the 19th of July, its height was 16 ft.; and from that period, at about 4 ft. or 5 ft. below the top, lateral buds began to make their appearance, which, as the stem grew, formed the peduncles on which the clusters of flowers expanded. On the 31st of July, the flower-stalk was 19 ft. high, when there were 13 lateral and alternate shoots thrown out. On August 15. there were 22 peduncles put forth, differing in length in proportion to their age, the lower ones measuring 2 ft. 6 in. in length, and bearing on their extremities numerous clusters of flower-buds; these subdividing, and giving space for each individual flower, and measuring across the clusters from 14 in. to 18 in. At this period, the height of the stem was 22 ft. 6 in. On the 7th of September, the flower-stem attained its extreme height, namely, 25 ft.; and the number of peduncles was 34, besides a cluster of flower-buds on the top of the stem. The first flower-buds began to expand on the 28th of September, and on the 10th of October the lowermost clusters were in great perfection. The flowers on the whole plant were carefully counted, and the number amounted to 5088, of the colour of sulphur, and above 5 in. in length. So richly were the flowers charged with a juice resembling the taste of honey, that it dropped from them in abundance, especially from about 9 o'clock in the morning until about 12 o'clock at noon. Bees came by myriads, and feasted themselves on the fast-flowing fluid. Observing such a quantity of the juice falling on the ground, I put vessels beneath to receive it as it dropped from the flowers, and filled six soda-water bottles with it. After being corked and rested a few days, it was acknowledged to be an excellent cordial; but after a while it fermented, became acid, and acquired a fetid smell.

"From the 10th of October to the middle of November, the stately appearance of the plant, with its gracefully curved branches expanding like candelabra, and sustaining such a number of erect blossoms and

buds, the flowers beautifully succeeding each other, presented to the eye a spectacle highly gratifying. The upper blossoms were in perfection so late as the 24th of December, when, a frost setting in, they were nipped; thus terminating the beauty of a plant that will long live in the recollection of its numerous visiters, the number of which, of all ranks, amounted to 7517. It may be worthy of remark, that, as the flower-stalk grew and the flowers expanded, the leaves of the plant became flaccid and drooping, and are now rapidly withering; but the stalk is still green, and will take several months to get dry.

"During its progress towards flowering, in order to secure it from the wind and rain, I erected over it a temporary covering with pit lights, and underneath a flight of steps to a platform 12 ft. from the ground, which enabled the visiters to approach the lowermost flowers. — T. Symons. Clowance, Feb. 1838."

Plates. Vol. IV. Dele the following, as being varieties distinguished by colour, and, therefore, not suitable for plates which, in the greater number of copies, will not be coloured : Magnolia grandiflora ferruginea (2), Tilia europæ a glaúca (16), Tília europæ'a rubra (17)." Dele “Liriodéndron Tulipífera obtusiloba (14), as being a variety readily understood from description." In a few copies, the plates of T. (e) álba, the Hungarian Lime, are named T. argéntea; and T. americàna is named T. álba. Acer obtusàtum, in a few copies, is named A. hýbridum. Though botanists are well acquainted with these synonymes, we have judged it advisable to name them here, for the sake of the general reader, and to enable the binder to arrange the plates properly.

OR,

THE TREES AND SHRUBS THAT ENDURE THE OPEN AIR IN GREAT BRITAIN
AND IRELAND,

PICTORIALLY AND BOTANICALLY DELINEATED, AND SCIENTIFICALLY AND POPULARLY DESCRIBED.

By J. C. LOUDON, F.L.S., &c.

THE nature of the Arboretum Britannicum is described in the advertisement on the last page of this sheet; and in the Gardener's Magazine for December, 1834. The object of this Return Paper is, to procure Notices of Trees and Shrubs, whether old or young, indigenous or foreign, hardy or half-hardy, of all the kinds mentioned below, from all parts of Great Britain, Ireland, and the Continent of Europe.

The Proprietor, Amateur, Nurseryman, Gardener, or Forester, who may receive this Paper, will greatly serve the cause of Arboriculture, if he will fill up with tne names and other particulars of such species of the genera enumerated as may be on his property, within the range of his observation, or under his care. The objects are: 1. To show the different degrees of progress which trees make in different localities and climates, and in different soils and situations; 2. To record the Arboretums, and also the smaller Collections of Trees and Shrubs that have been made in different places; and, 3. To notice Specimens remarkable for their bulk, age, beauty, singularity, or peculiarity of form; or, in the case of very young trees, for their rapidity of growth. It is requested that this sheet, when filled up, may be returned to the undersigned, at Messrs. Longman's, 39. Paternoster Row, London, at the earliest convenience of the party to whom it is addressed. London, Nov. 1834; May, 1835; and July, 1835.
