The dressing your friend has given his Pear-trees should destroy the scale. If it does not, let him, as soon as the leaves drop next autumn, dress them with a mixture of equal parts of train-oil, turpentine, and spirits of tar - taking care to avoid the wood and fruit-buds. We have killed the scale with this mixture, but it is severe on the trees for the first season after its application.
When we tell you that we recollect of its once being asserted in the same journal that hot-water pipes were useless in Pine-pits, and that gardeners put them in such structures for the sake of the discount they got out of them!! you may, like us, think very lightly of any scandal which is poured upon us from the same quarter now. We hope all who are worthy of the name of "Gardener" will survive such libels. We have no intention of entering on a defence in these pages; it is not necessary.
The heaviest bunch of Grapes that we have any knowledge of, was grown and exhibited by Mr James Dickson, Arkleton Gardens, Dumfriesshire. It weighed 19 lb. 5 oz. Mr Fowler produced a bunch something over 17 lb., and long ago Mr Speechly produced one 19 lb. weight. No doubt these weights may yet be exceeded.
We observe the pruner recommended by Mr W. Thomson, in his treatise on the Vine, is advertised by Messrs Stewart & Mein, Kelso; and, doubtless, they can be had of others in the trade, probably from Mr Thomson himself.
