Artificial Fertilizers for Raspberries and Other Fruits. 



05 1* Sir, — What is the best fertilizer for raspberries ? How much is best to apply 

 to a hill, or to an acre of berry bushes ; soil, a strong clay loam. 



W. P. R., Oshawa. 



Probably half a pound each of superphosphate and of muriate of potash^ 

 would not be too much for raspberry bushes. This could be applied at any 

 time ; and in the growing season, nitrate of soda about an equal quantity. 

 Which of these fertilizers your soil most needs, and the amount, can only be 

 proved by actual experiment, and it would be well to try the phosphates on 

 one portion and the potash on another, keeping careful notes of the results. 



Trees for Street Planting^. 



O'^SS. Sir, — The village of East Toronto have under consideration the planting of 

 all their graded streets on some uniform system. I would like your opinion with regard 

 to the trees niost suitable for the purpose. The trees native to the place are the pine, 

 black and white oak, with an occasional maple, but this last tree does not seem to be a 

 long liver with us, for when they are four of hve inches in diameter they die off, probably 

 because the roots reach the dead sand which underlies our surface soil. The plan recom- 

 mended to us by an experienced amateur is to plant trees forty feet apart from side to side 

 of the street, and, if elm will grow in our soil, to plant these sixty or seventy feet apart, 

 giving permission to the owners to plant other trees between, if they desire. On our main 

 streets and on the streets where the electric cars run, we propose to plant the trees fifty 

 feet apart from side to side, in place of forty. 



R. Morton, Torontd, Out. 



It is a very important matter to select the proper kind of tree for such 

 planting. The maple is somewhat unsatisfactory in certain conditions of soil 

 and climate, and where it does make a thrifty and vigorous growth, the foliage 

 is too dense for a street tree ; besides, it so completely hides the view of the 

 buildings and shuts in from the inhabifants every pleasant prospect, that we do 

 not at all admire it for the street. The oaks are magnificent trees, but rather 

 rugged in appearance, and entirely lacking in that gracefulness which should 

 characterize street shade trees. We know of no tree that will be as suitable for 

 your purpose, providing it is adapted to your soil, as the American W^hite Elm 

 (Ulmus Americana). This tree grows to a height of eighty oc more feet. Its 

 arching limbs at a lofty height give it a most graceful appearance, and it is not 

 so dense as to close in the pleasant prospect. The trunk and larger branches 

 are often heavily covered with short and leafy boughs, and streets planted with 

 these trees become columned and arched like the aisles of a cathedral. Any 

 one who has visited the city of Syracuse, N. Y., will be impressed with the mag- 

 nificence of this tree. Several of the finest avenues are thus arched, both over 

 the carriage-way and the foot-path, with these noble trees ; the elms of Boston 

 are also famous. Do not mistake and plant the Slippery Elm (Ulmus fulva), 

 which is very common in Canada, in place of the American elm, for it is a tree 

 which does not reach more than half the height of the White elm, and in every 

 way is inferior to the other. The distances which you mention for the planting 

 the trees apart are about right.
