from sudden changes of temperature. The house is a very good one, and 
it is fitted up with more attention to comfort than most others that we 
have seen. The library in particular was a delightful room. 
September 28.— Yorkshire Museum. —The building is placed in the 
grounds belonging to the fine ruins of St. Mary’s Abbey, and these 
grounds are laid out as a botanic garden. Among the plants, which were 
all named, was a fine specimen of Lupinus arboreus , with a branching 
stem nearly six feet high ; and another of Lupinus polyphyllus, which had 
young shoots opening instead of pods on the flower-stem. 
Backhouses Nursery. Here was a large stock of the beautiful Heli- 
chrysum retortum , Dimorphotheca ( Calendula ) graminifolia , and Chry¬ 
santhemum atratum (the Helichrysum having been imported from South 
Africa by Mr. James Backhouse), and many other interesting plants. 
The Cemetery at York has too much the appearance of a garden. There 
is an avenue of lime-trees, and the groves are planted with flowers. 
There was a fine terrace along the upper end, which was ascended by 
three flights of four steps, each flight being cut out of a single stone.

ON DESTROYING CATERPILLARS ON ROSE-TREES, GOOSEBERRY 
BUSHES, AND OTHER PLANTS. 
BY MR. SCHLENTHER, NURSERYMAN IN TILSIL. 
(Translated from the Garten Zeitung.) 
At the time when the buds are just unfolding themselves on the rose- 
trees, a number of small green caterpillars generally make their appear¬ 
ance, and begin to eat the small buds. I immediately make a strong 
decoction of common tobacco-leaves; I let it get quite cool, and, 
when the dew has completely evaporated, I sprinkle the tree all over 
every morning, by means of a watering-pot with the rose on, till every 
part is thoroughly embued with it. I continue this operation three or 
four days in succession ; and, should rain come on about the time of 
sprinkling, so that the liquid is washed away, as soon as the fo'liage is 
dry the sprinkling must again be repeated. It will soon be found that 
the caterpillars will all disappear, and the undisturbed buds will then 
unfold themselves. I have practised this method for several years with 
the greatest success, and never indeed found it to fail; so much so, that 
even buds that were pretty far advanced and almost eaten through by the 
caterpillars, soon began to unfold the remaining mutilated parts.
