Moth to Gooseberry and Currant; of those of the Fox-coloured 
Sawfly to Pine, and the very interesting observation (for which I 
am indebted to Dr. W. Somerville, Prof, of Forestry in the 
University of Edinburgh) of attack of our common “ Pine Beetle ” 
to Larch. Observations of Eelworm attacks to Bean and to 
Strawberry plants, and the peculiar malformed growths thence 
arising, have not been recorded before save in my official reports 
for the Journal of the Boyal Agricultural Society of England, in 
which importance of space does not allow of full technical ento¬ 
mological details. 
Great advance has been made in the past year as to the long- 
needed point of introduction of treatment which might be brought 
to bear when occasion called for it, in clearing off the hordes of 
moth caterpillars, which yearly, with the appearance of the 
spring leafage, had pretty much at their own pleasure ravaged 
the trees of our chief orchard growers. As full details of the 
means employed both for prevention and remedy, respectively, 
of autumn establishments and of spring injuries will be found 
under the heads of “ Sticky-banding,” “ Paris-green,” &c., it is 
unnecessary to do more here than to refer to them. 
Advance has been made also in methods of applying insecti¬ 
cides, by introductions of new forms, and also by better adaptations 
of old forms of spraying machines, so that these are now pro¬ 
curable, suited as may be needed for the various requirements of 
orchard growth crowded by under-cropping, of more open space 
giving room for use of hand-barrow sprayer with much higher 
delivery up to 40 or 50 feet; or the Strawsonizer in its different 
forms for field and orchard use, of which the good report on its 
many trials as to delivery, both of dust and spray dressings, has 
been so often before us as to make it great matter of regret that 
the issue was so long delayed. 
That advance has also been made in appreciation (in some of 
the highest quarters) of the necessity of adding knowledge of pre¬ 
vention of the ravages of crop insect pests to other branches of 
agricultural education, has been shown by the addition, in the 
past year, of agricultural entomology as a voluntary subject, to 
the papers set at the Senior Examination by our Boyal Agricul¬ 
tural Society : also by examination on the same subject being 
now made compulsory at the Boyal Agricultural College, Ciren¬ 
cester; and the subject is also receiving attention amongst the 
points of agricultural education which are especially taken up at 
the University College of N. Wales, at Bangor. 
The endowment of a Lectureship in connection with the Chair 
of Agriculture in Edinburgh University, named, in remembrance 
of the liberal foundress, the “ Steven Lectureship,” has already 
in its opening course proved another helpful aid in advancement 
of serviceable knowledge of agricultural entomology. In the well
