PLANTING DAHLIAS 



Many make an error when they 

 plant their dahlias, whicli effects their 

 entire results. 



Many plant too many tubers in a 

 hill, with the result that they receive 

 several stalks, a surplus of foliage, and 

 a few flowers. One tuber is sufficient, 

 two a great plenty, and more than 

 that number a detriment. 



Another mistake many have made, 

 is that they stand the tuber on its end, 

 thinking by so doing they are helping 

 it to come through the ground, by get- 

 ting the sprout near the top of the sur- 

 face, while in reality they are doing 

 the plant harm. 



Tubers should be laid flat down, be- 

 tween five and seven inches deep, with 

 sprout or eye facing upward. The new 

 tubers which form, when planted In 

 this manner will form sufficiently deep 

 and receive plenty of moisture, while, 

 If they were planted with the t»Der 

 standing on its end", the new tubers 

 would form near the top of the ground, 

 and the plant would become stunted, 

 or would not be able to give best re- 

 sults, which would show in lack of 

 blossoms.

NEW BOOKS 



La-ndscape Architecture, by Henry 

 Vincent Hubbard and Theodora Kim- 

 ball, Harvard University Press, Cam- 

 bridge. Price $1.50 postpaid. 



Henry Vincent Hubbard, Assistant 

 Professor of Landscape Architecture 

 at Harvard University, and Theodora 

 Kimball, Librarian of the School ot 

 Landscape Architecture at the same 

 institution, have collaborated in pro- 

 ducing a volume which although bound 

 in paper should be of enduring value 

 The rapid growth of landscape archi- 

 tecture has made very desirable a gen- 

 eral scheme of classification, and the 

 one which has been worked out at Har- 

 vard is the first of the kind to be pre- 

 sented between covers. It can be used 

 by practitioners, librarians and stu- 

 dents.
