the winter, and the lateness of the spring, the annuals, &c., were late in coming 

 into flowei". As we formerly noticed, the borders along the walks are planted 

 with trees and shrubs, according to the natural order of Jussieu, This ar- 

 rangement is now attracting considerable interest, from the name of each tree 

 being placed in front of it, upon tallies of patent zinc, written with ink that 

 resists the action of the atmosphere. Each tally contains the botanical and 

 common name, the family it belongs to, the native country, the height it 

 attains when full grown, and the year it was planted in this ground, with its 

 height at that time ; thus ; — 



Salix babylonica. 



Weeping Willow. 



Amentaceae. 



Levant. 



40 ft. 



1837. 



3 ft. 



Populus macrophylla. 



Ontario Poplar. 



Amentaceae. 



North America. 1837.

The shrubs belonging to each family, which are planted between the trees, are 

 to be named with tallies of rather a different appearance. By attending to 

 these explanations, a considerable degree of popular knowledge of botany may 

 be very easily attained. The public are indebted for this rational enjoyment 

 to the advice and assistance of Mr. Daniel Urquhart of Blackness Nursery, 

 whose attention to this department has been unremitting. {Dundee Courier, 

 Aug. 2 1.1838.) 



[We should be much obliged to Mr. Urquhart for a list of the trees and 

 shrubs planted in this burial-ground ; and, if not inconvenient, for a ground 

 plan of it, showing their arrangement. Any particulars respecting the soil, 

 draining, &c., would be very acceptable. See what we have said on the 

 subjects of laying out and planting churchyards, in the Architectural Ma- 

 gazine for July. — Cond.}

The Belfast Botanic Garden contains a number of araucarias and other 

 South Sea Island plants ; among which are several specimens of phyllocladus, 

 a most remarkable tree, bearing in its foliage some resemblance to salisburia, 

 and never before, we believe, seen in a living state in this country. We 

 should feel much obliged to the curator, if he will send us some details re- 

 specting these, and other rare plants in his garden. In the Belfast Northern 

 Whig for August 30th, it is stated that Professor Morren of Liege (see p. 443.) 

 found the Belfast Garden superior to any other in Ireland. — Cond,

A Mining Grub, very injurious to pear trees, abounds in this neighbourhood. 

 It differs from some species of leaf miners, in not making a circuitous or zigzag 

 tract; I)ut the leaves appear blotched with roundish dark-coloured spots, 

 from a quarter to half an inch in diameter. This species of insect is very 

 difficult to destroy, on account of the cuticle of the leaf protecting the grub 

 from every kind of external application. If a few leaves with the insect will 

 be of any use, I shall be happy to forward them to you. — John Jennings. 

 Shipston on Stow; Aug. 21, 1838. [We have written to Mr. Jennings for spe- 

 cimens, and, having received them, we hope, through the assistance of Mr. West- 

 wood, to be able to give some account of the insect in our next Number. — Cond.]
