“ But there is another interesting point in this investigation. Do the 
newly originated sorts really maintain in the unfavourable districts the 
appearance of perfect health ? Are the new Pears uniformly healthy 
when the old ones are always feeble? Undoubtedly this question must 
be answered in the negative. Some of the latest Flemish Pears already 
exhibit symptoms of decay or bad health in these districts.” 
From the foregoing long extracts the writer in the “ Scottish Gardener ” 
will see, that, though there are, like himself, some advocates of Mr. 
Knight’s theory in America, facts are all against them.

CUPRESSUS LAWSONIANA. 
We were pleased to see at the Regent Street rooms the last meeting 
half a dozen plants of this fine Cypress exhibited by Messrs. Waterer 
and Godfrey, who hold the principal stock of it; as some parties have 
considered it identical with Thujopsis borealis, plants of both were 
exhibited, very much to the advantage of the Cypress, which is the 
most graceful and beautiful of its family. From what was said by 
Dr. Bindley of its habitat, little doubts exist but that it will prove 
hardy, and consequently become a valuable addition to our out-door 
Conifera3. 
HORTICULTURAL EXHIBITIONS AND PLANT 
EXHIBITING. 
Now that the great summer exhibitions are over, it appears a fitting 
opportunity to bring them under review, with the object of stating 
what we consider defective in classing plants for exhibition, as well as 
their after arrangement in the tents ; and likewise to invite exhibitors 
to state their opinions on this subject, that managers of exhibitions 
may have the advantage of the discussion in framing their schedules 
for another season. 
In the first place, no objection can be made to such natural groups of 
plants as Orchids, Lycopods, Ferns—to interfere with which would in 
a great measure destroy the charm of these exhibitions, than which, 
when shown by themselves, nothing can be more interesting and 
beautiful. The same may be said of Heaths, Chinese Azaleas, and 
Rhododendrons, when shown in separate classes, as they form natural 
groups, and possess sufficiently distinctive features, as regards colour, 
to produce effect. We may take variegated plants in the same sense 
as to colour, and add that, although any of the last named may be— 
and very frequently are—mixed with other plants for forming collec-
