A review of the work of the Experimental Farms . e mixed plantations weremaking the most satisfactory growth, and are still making bet let-growth than some of the trees in clumps of single species, but tin-rapid growing kinds are developing so fast in the mixed belt thatthey are overshading some of the more valuable trees, and thosethat cannot endure shade are being killed. To some extent thisovershading is prevented by clearing the side branches and lettingin more light, and by heading back some of the trees of less nature the proper proportion of rapid and slow growing, shade-enduring and light-needing trees is gradually adjusted as the treesdevelop, but in artificial planting it is very difficult to arrange them 6o in proper proportion, especially when a large number of species areused. The fewer kinds that are used the easier it is to plant thetrees in the best proportion of each kind of tree. In some of the clumps of single species the disadvantage of nothaving two or more kinds mixed is quite as apparent as the disad-.

Ash,butternut, black walnut, and elm, which have thin foliage, do notkill the sod when young, and the growth on this account is other heavy foliaged kinds, such as larch, spruce, pine or box elderhad been mixed with these the results would almost certainly havebeen better. THE WORK OF THE CHEMICAL DIVISION. The relationship which exists between agriculture and chemistryis a very close and intimate one. Whether he understands it or not,the farmer who carries on his operations in the field, the feed lot,or the dairy according to correct methods is putting into practicaloperation the principles of agricultural chemistry. The require-ments of crops and animals, the character and deficiences of soiK,the means by which soil fertility may be most economically builtup and maintained, the nature and a
