300 ANNUAL REPORT 



added to our list last spring: Populus Boleanna, Populus Siberica, 

 Populus Wobsky, Populus Bereolensis, P Alba Angustea and Salix 

 Fragilis. The wood of the latter is said to be valuable, being 

 light and tough and durable in moist situations. 



FOREST AND ORNAMENTAL TREES AND SHRUBS. 



Quite a number of trees of doubtful hardiness have been 

 planted. Some have been placed on the north-east side of a snow 

 fence four feet distant to try the effects of shade. As there is no 

 dividing line between trees and shrubs I have concluded to culti- 

 vate a few varieties of such shrubs as will stand our winters with- 

 out protection, and will pay especial attention to natives of Min- 

 nesota. The following were planted in spring of 1889: of arbor- 

 vitas the globosa, gigantea, orientallis, plicata, Siberica; the stone 

 pine, eastern spruce, Nordmans silver fir, Hooker's hemlock, 

 Calabrian pine, red pine, white spruce, American yellow birch, 

 black birch, American white birch, black walnut, wild black 

 cherry, buckeye, Tea's weeping mulberry, hop-tree, Kentucky 

 coffee tree, Norway maple, English maple, mountain maple, oak 

 leaf mountain ash, European mountain ash, American mountain 

 ash, American sycamore, tulip tree, cucumber tree, Japan cypress, 

 American beech, horse chestuut, American rock elm, English elm, 

 Scotch elm, American white elm, hawthorn, hornbeam, black 

 thorn, dwarf Juneberry, privet, purple leaf Berberry.Crategus san- 

 guinea (thorn), wild cranberry from Wisconsin, bearberry, black- 

 berry and bush blueberry from Wisconsin woods, Artemesia abra- 

 laus, Phox, Ribes 148 vor. (currant) Eleagnus Angustifolius, high 

 bush cranberry, Rosa rugosa (Japan rose), Spirea, Philadelphus, 

 Spirea Dounglassii, Spirea Van Houtii, Spirea Derxiea, Spirea rup 

 and Spirea nobleanna. I regret to state that some of these trees 

 were inferior in size and quality, arrive! in bad order and proved 

 almost an entire failure. Most of them, however, are alive but 

 have not made satisfactory growth. I trust that the mistake of 

 buying very cheap trees will not be repeated. 



I supposed that sweet chestuut trees grown from nuts would 

 show leaves more than one season, but they didn't. Downing's 

 Mulberry has gone with them. Weir's cut leaf maple is well 

 started, only one sprout left. 



Small trees of catalpa and Russian mulberry killed to the ground 

 last winter but have sent up vigorous sprouts. Most catalpas six 

 feet high are making some growth. The red cedars now growing 

 on the Station, though said to have been grown from Northern 

 seed, have not given satisfaction. Perhaps there was a mistake 

 about the seed. 



Of evergreen trees planted about the school grounds the balsam 

 fir has died out worse than any other kinds, and I predict that in a 

 few years from now the balsam fir, box elder and European alder 

 will only be planted for the sake of variety; for the white spruce 

 is much better than the balsam fir and the soft maple is better than 

 the box elder. The one serious objection to the soft maple that it 

 splits down in storms may be partially removed. If grown thickly 

 in groves not many forks will form and lone trees may be pruned
