Soil, Situation, Sfc. The Lombardy poplar will only thrive on a tolerablygood soil, and will not attain a large size, except in a situation where to agood soil is joined proximity to water. In the climate of London, it growswith such rapidity, that care is required, when it is introduced in ornamentalplantations, to thin it out, or cut it down, so that its form may not prepon-derate- in the landscape. In the north of England, and in most parts ofScotland, it does not thrive.

Statistics. Recorded Trees. Dr. Walker mentions a tree on the borders of a canal, near Brussels,which, in 15 years, attained the height of 80 ft., with a trunk from 7 ft. to 8 ft. in circumference.Another tree, at Nisbet, in Berwickshire, had, in 1795, attained the height of 60 ft. in 26 years; witha trunk 6 ft. 1 in. in circumference at 4 ft. from the ground. The largest tree that Sir Thomas DickLauder knows of in Scotland stands on the lawn, a little below the Castle of Tarnawa, in Morayshire.Phillips says the most extraordinary Lombardy poplars which he had seen were on the banks of theSeine, near Rouen. They had not been planted more than 20 years; “ yet their height is such, as tomake it quite awful to walk in the avenues.” ( St/l. Flor. t vol. ii. p. 133.) We wrote to our friend, theAbbfe Gosier of Rouen, for some account of these trees; and his answer, dated March 4th, 1837,states, on the authority of M. Dubreuil, Conservator des Promenades publiques, &c., that theygrow in alluvial soil, and are 150 ft. high. A tree, planted in 1758, in the St. Peter’s Nursery, Can-terbury, was blown down, Mr. Masters informs us, during the hurricane of Nov. 29.1836. The trunkwas upwards of 5 ft. in diameter at 1ft. from the ground, and at 6ft. it was 4 ft. 4 in. in diameter.It was nearly 100 ft. in height, very symmetrically formed, and from the northern and westernentrances to Canterbury was an object of considerable attraction. The wood of the trunk was in acomplete state of decay, and had produced an abundance of Polfrx>rus igni^rius for several years past
