the Government buildings, the town-hall, a theatre, two hospitals, a public library, and a convent of the Presentation Order. The population was 10,100 in 1847, 10,668 in 1870, and 12,753 in 1881. Launceston began to be an important settlement not long after the first colonization of Tasmania. St John's Church (Episcopal) dates from 1824. The town was incorporated in 1858.

LAUREL. There are at least four shrubs or small trees which are called by this name in Great Britain, viz., the common or cherry laurel (Cerasus Laurocerasus, Lois.), the Portugal laurel (C. lusitanica, Lois.), the bay or sweet laurel (Laurus nobilis, L.), and the spurge laurel (Daphne Laureola, L.). The first two belong to the rose family (Rosaceæ), and are regarded by Bentham and Hooker as a subgenus of Prunus, L. (Genera Plantarum, i. p. 610), to which genus Linnæus referred them.
The common laurel is a native of the woody and sub- alpine regions of the Caucasus, of the mountains of northern Persia, of north-western Asia Minor, and of the Crimea. It was received into Europe in 1576 (De Can- dolle, Prod., ii. p. 540), and flowered for the first time in 1583. Ray in 1688 relates that it was first brought from Trebizonde to Constantinople, thence to Italy, France, Germany, and England. Parkinson in his Paradisus records it as growing in a garden at Highgate in 1629; and in Johnson's edition of Gerard's Herbal, published in 1633, it is recorded that the plant "is now got into many of our choice English gardens, where it is well respected for the beauty of the leaues and their lasting or continuall greennesse" (see Loudon's Arboretum, ii. p. 717). The leaves of this plant are rather large, broadly lance-shaped, and of a leathery consistence, the margin being somewhat serrated. They are remarkable for their poisonous properties, giving off the odour of bitter almonds when bruised; the vapour thus issuing is sufficient to kill small insects. Cherry laurel water is a solution of the volatile oil. The leaves when cut up finely and distilled yield the oil of bitter almonds and hydrocyanic (prussic) acid. Sweetmeats, custards, cream, &c., are often flavoured with laurel-leaf water, as it imparts the same flavour as bitter almonds; but it should be used sparingly, as it is a dangerous poison, having several times proved fatal. The first case occurred in 1731, which induced a careful investigation to be made of its nature, which was discovered by Schrader in 1802 to be hydrocyanic acid. The effects of the distilled laurel-leaf water on living vegetables is to destroy them like ordinary prussic acid; while a few drops act on animals as a powerful poison. It was introduced into the British pharmacopœia in 1839, but is more generally superseded by the use of hydrocyanic acid. The following varieties of the common laurel are in cultivation: – the Caucasian (Prunus Laurocerasus caucasica), which is hardier and bears very rich dark-green glossy foliage; the Versailles laurel (P. L. latifolia), which has larger leaves; the Colchican (P. L. colchica), which is a dwarf-spreading bush with narrow sharply serrated pale green leaves. There is also the variety rotundifolia with short broad leaves, the Grecian with narrow leaves, and the Alexandrian with very small leaves. See Hemsley's Handbook of Hardy Trees, &c., p. 141.
The Portugal laurel is believed to be a native of Portugal and Madeira. This tree, together with a variety called Hixa, Ser., which bears larger leaves and has the flowers more loosely disposed, were found growing together in 1827 on the Serra de Gerez in Portugal, the former being 20 feet high while the latter attained to 70 feet. It was introduced into England about the year 1648, when it was cultivated in the Oxford Botanic Gardens. During the first half of the 18th century this plant, the common
laurel, and the holly were almost the only hardy evergreen shrubs procurable in British nurseries. They are all three tender about Paris, and consequently much less seen in the neighbourhood of that city than in England, where they stand the ordinary winters but not very severe ones. There is a variety (myrtifolia) of compact habit with smaller narrow leaves, a variegated variety, and one of recent introduction (azorica), probably not so hardy as the Continental form. See Handbook of Hardy Trees, &c., p. 141.
The evergreen glossy foliage of the common and Portugal laurels render them well adapted for shrubberies, while the racemes of white flowers are not devoid of beauty. The former often ripens its insipid drupes, but the Portugal rarely does so. It appears to be less able to accommodate itself to the English climate, as the wood does not usually "ripen" so satisfactorily. Hence it is rather more liable to be cut by the frost. According to Prof. A. Gray neither the common nor the Portugal laurel stands either the summer or the winter climate of the United States.
The bay or sweet laurel (Laurus nobilis, L.), belongs to the family Lauraceæ, which contains sassafras, benzoin, camphor, and other trees remarkable for their aromatic properties. It is a large evergreen shrub, sometimes reaching the height of 60 feet, but rarely assuming a truly tree-like character. The leaves are smaller than those of the preceding laurels, possessing an aromatic and slightly bitter flavour, and are quite devoid of the poisonous properties of the cherry laurel. The small yellowish-green flowers are produced in axillary clusters, and consist of a calyx only, which encloses nine stamens in the male, the anthers of which dehisce by valves which lift upwards as in the common barberry, and carry glandular processes at the base of the filament. The fruit consists of a succulent berry surrounded by the persistent base of the calyx. The bay laurel is a native of Italy, Greece, and North Africa, and is abundantly grown in the British Isles as an evergreen shrub, as it stands most winters. The date of its introduction is unknown, but must have been previous to 1562, as it is mentioned in Turner's Herbal published in that year. A full description also occurs in Gerard's Herbal, 1597, p. 1222. It was used for strewing the floors of houses of distinguished persons in the reign of Elizabeth. Several varieties have been cultivated, differing in the character of their foliage, as the undulata or wave-leafed, salicifolia or willow-leafed, the variegated, the broad-leafed, and the curled; there is also the double-flowered variety. The bay laurel was carried to North America by the early colonists, but, like the others, apparently does not thrive there.
This laurel is generally held to be the Daphne of the ancients,
though at least Dr Lindley, following Gerard (Herbal, 1795,
p. 761), asserts that the Greek Daphne was Ruscus racemosus.
Among the Greeks the laurel was sacred to Apollo, especially in
connexion with Tempe, in whose laurel groves the god himself
obtained purification from the blood of the Python. This legend
was dramatically represented at the Pythian festival once in eight
years, a boy fleeing from Delphi to Tempe, and after a time being
led back with song, crowned and adorned with laurel. Similar
5a.(f>i>ri<t>opiai were known elsewhere in Greece. Apollo, himself
purified, was the author of purification and atonement to other
penitents, and the laurel was the symbol of this power, which came
to be generally associated with his person and sanctuaries. The
relation of Apollo to the laurel was expressed in the legend of
DAPHNE (q.v.). The victors in the Pythian games were crowned
with the laurels of Apollo, and thus the laurel became the symbol
of triumph in Rome as well as in Greece. As Apollo was the god
of poets, the Laurea Apollinaris naturally belonged to poetic merit,
and so we still have a poet laureate. The various prerogatives of
the laurel among the ancients are collected by Pliny (Hist. Kat., xv.
30). It was a sign of truce, like the olive branch; letters announcing
victory and the arms of the victorious soldiery were garnished with
it; it was thought that lightning could not strike it, and the
