DEPARTMENT KEPORTS. G9 



We have ]i)laiitecl about seventy-five varieties of corn, over twenty of onions, 

 and about 250 named varieties of potatoes, besides about as many more 

 imnamed seedlings which have originated at tlie College. 



We have pruned some limbs from two api)le trees on the twenty-fifth day of 

 each mouth in the year, to see wliich will thrive the best. 



To the row of mulched trees (sec previous report) we have added a small 

 wagon load of old straw to each tree. On a row by the side of this we have 

 spread broadcast to each tree a wagon load of leached ashes. Another row is 

 well manured, but left in grass. We are bandaging all of our apple trees to 

 catch the moth, and inducing our neighbors to do the same. We strip the 

 fruit fronr some trees in full bearing to change the bearing year. We are 

 sprinkling slaked lime on some trees and gypsum on others to observe the 

 effect on the codling moth, leaves, fruit, etc. Numerous other experiments 

 are going on in attempting to destroy the codling moths. AVe have added 

 thirty varieties of the best apples from southern Ohio. We sent to southern 

 Ohio for pollen of apple flowers to use here in making crosses. We layered 

 one apple tree to get young trees of equal quality for future experiments. We 

 continue the ex])eriments with the trees in grass described year before last. 



We have received, by purchase, forty-one new unnamed varieties of grapes 

 from Haskell, of N. Y. We sent to Ohio for pollen of flowers of the grape, 

 which was used in fertilizing some flowers at this place. We have set 300 of 

 our seedling grapes between the 300 named sorts in the new vineyard. 



To the arboretum we have added rows of seeds of blue ash, shag-bark hick- 

 ory, Judas tree, yellow-wood, white-oak, scarlet-oak, white-wood, rock elm, and 

 small quantities of other species of trees. 



For experiment, we have planted pits of peaches diseased with the yellows. 

 We have small samples of hedges of honey locust, osage orange, pepperidge, 

 wild crab-apple, wild plum, hawthorn, prickley ash; also, of arbor vita^, Siber- 

 ian arbor vita?, Austrian pine, Norway spruce, lilac, spiriea, etc. 



The arboretum contains a large variety of other seedlings. We grafted 

 potatoes on tomatoes, and artichokes onto sunflowers ; continued the planting 

 of black-wax beans which were crossed v/ith foreign stock, and shall com- 

 pare them with those not so crossed ; also continue to raise the corn last year 

 crossed with foreign stock. 



We have obtained Yellow Danver's onions, which have been raised for forty 

 years by Gregory of Marblehead, also some of the same variety from Connecti- 

 cut. We shall cross the flowers of these, also save some seeds of each pure for 

 comparison of results. 



We continue to raise some twenty varieties of Japan vegetables, such as 

 ripened seeds last year. These consist of squashes, beans, cucumbers, onions, 

 radishes, and lettuce. 



We are testing ten or more of the best varieties of tomatoes, and have crossed 

 the Conqueror (best of all last year), with a smooth early sort. 



We have crossed the flowers of Clawson wheat with Diehl, and have root 

 pruned these also. 



We have crossed flowers of two varieties of gooseberries; also black cap rasp- 

 berries with red raspberries. 



We are root pruning dent corn and some other sorts to observe the effect 

 on the yield. We are trying the same on tomatoes, turnips, cabbages, and 

 perhaps we may do the same on other plants. 



We intend to bury in bottles numerous kinds of seeds to dig up at remote 

 intervals for testing their vitality.
