evaporation, keeps the soil from becoming dry, and maintains it in 
that moist and equable condition of temperature most favorable 
to the requirements of young roots. 
Planting tree dahlias and ornamental beet around the flower 
borders is now being proceeded with. 
Summer pruning the peach and the pear gives the students 
plenty to occupy their hands and mind. 
When a tree bas arrived at the age of three or more years, 
summer pruning is not required so much. 
Mixing manures for fruit trees in the orchard is now being 
attended to. 
The students are kept busy fighting the pear and cherry slug 
(Selandria cerasi). This little destructive insect is easily seen 
with the naked eye when in the larva state ; it is a small dark- 
greenish slimy caterpillar, found on the leaves of the pear, cherry, 
and other trees, which they injure very much by gnawing the 
epidermis off the upper portion of the leaves and leaving the 
under side untouched. 
Dusting the infested trees with dry sand will kill the slug, but 
not its eggs. 
Spraying the trees with a mixture of soft soap and water also 
kills the slug, but not its eggs. The proportions used are 2 ozs. 
to a gallon of water. 
Hellebore powder—at the rate of 1 lb. to 20 gallons of water, 
and sprayed on the tree—is found to be the most effective remedy 
for the prevention of this pest. 
Ploughing in the orchard with the aid of the horse, and 
hoeing, digging, and weeding give some of the students 
occupation. 
Planting egg and chili plants is now being attended to. 
Mowing grass on the lawns with a scythe and planting seed 
of the sugar beet and beans in the lower orchard give us plenty 
to do. 
Beans are now being set, the distance apart of the rows being 
2 feet. 
The list given below enumerates some of the best grown :— 
Emperor William, Canadian Wonder, Golden Waxpod, Ne Plus 
Ultra, &e. 
Thinning out onions in the lower orchard gives work to the 
students. 
Rooted chrysanthemums are now being planted in the nursery. 
The following are some of the best grown :—Sunset, Mrs. H. 
Cannell, Lady St. Clair, Gold, Sunflower, Lady Lawrence. There ° 
are a great many more varieties, but too numerous to mention. 
Mr. McAlpine’s experimental wheat plots look very well. Mr. 
Greenlaw has got the looking after them. 
Cutting dead-wood out of oranges gives us work.
