My object, however, at present is not to go into the subject of 
wall-tree systems, or to criticise their respective merits, but to 
call attention to the fact that a wall tree upon the Devonshire 
system, and a standard in the open, are growing very much under 
the same conditions; the wall tree has a slightly warmer berth, but 
presents only one side or face to the light. In the standard the whole 
is exposed to all the benefit of climatic action—that is, to sun, wind, 
and rain, of which probably wind is not the least important. When 
a wall-trained plant is allowed to grow free, the young shoots, 
lengthy and pliable as they are in the case of the Dig, soon yield to 
the weight of foliage at their extremities, bending outwards and 
downwards, till at the end of the season they have taken a hori¬ 
zontal or even hanging condition ; the last inch or two of growth 
being curved a little upwards from the effort to regain the natural 
vertical position of normal plant growth. 
The tree has been in fact training itself horizontally, and the 
result is the production of strong, short-jointed, fruiting wood. 
In conclusion, as I am merely recording an experiment, and not 
nursing, so to speak, a hobby, I feel bound to note everything, 
whether of the nature of success or of drawback. In cold un¬ 
favourable autumns the fruit of the Marseilles would drop off when 
ripe after a cold night or too, and, though very sweet, would be 
somewhat flaccid and watery. A few fine days, however, would put 
a stop to this. Also, a few late-growing gross shoots will fail to 
ripen their fruit-bearing extremities, which then perish in 
the winter. Three years ago, however, root-pruning checked this 
evil, and the process was repeated this last November.

Ix continuing the series of notes on the diseases of the Yine it is 
proposed to limit the present communication to those classed by 
mycologists under the genera JPhyllosticta , Septoria , and their imme¬ 
diate allies. It may be premised that the fungi of this type are 
seldom really destructive in their influence, but exceptions to this
