How Tall Should a Raspberry 

 Bush Be? From crosses between 

 ordinary raspberries and Rubus 

 chamaemorus, the bakeberry of the 

 jiorthern swamps, we are now get- 

 ting fruitful, hardy raspberry plants, 

 ranging at maturity from one to six 

 feet in height, with some of the most 

 productive from three to four feet 

 in height. As tall raspberry plants 

 which have the tops cut oft lose the 

 Lest bearing wood in the process, 

 plants which will not require top- 

 ping are now in sight. These should 

 also be more or less protected by 

 snow during the winter months and 

 may, therefore, be less winter in- 

 jured. At any rate, we now have 

 the possibility of raspberries pro- 

 duced on any height of plant you 

 wish.

New Hampshire Wild Blueberries 

 Used to Improve Cultivated Varie- 

 ties. Increased hardiness is needed 

 for blueberry varieties to be fully 

 adapted to New Hampshire condi- 

 tions. Crosses of a large-fruited, 

 wild high-bush blueberry, found in 

 Loudon, have been made with sev- 

 eral of the improved cultivated blue- 

 berries from New Jersey and Mary- 

 land . Also, crosses of the cultivated 

 high-bush variety, Pemberton, have 

 been made with superior wild low- 

 bush blueberries. The F^ hybrids of 

 this cross proved to be half-high and 

 had dark blackish-blue fruits. In 

 the Fo generation, of which several 

 thousand seedlings are being grown, 

 good light blue fruits should occur. 

 One thousand unnamed blueberry 

 seedlings, grown and furnished by 

 the U. S. Department of Agriculture, 

 are being grown for a fruiting test 

 at Durham and Gilford.

Anti-Biotic Being Tested on 

 Squashes. A new anti-biotic derived 



from the same organism which pro- 

 duces streptomycin has been report- 

 ed by Michigan State College to be 

 effective in preventing the growth of 

 fungi. This material, actidione, was 

 tried this winter on some Butternut 

 squashes by cutting off at the stem 

 end, dipping in a paste of rotten 

 squash, and then in the actidione 

 solution. While squashes treated in 

 this way finally rotted, decay was de- 

 layed for a considerable length of 

 time. Hence, it seems desirable to 

 try this material more extensively 

 another year.

A New, Early Lima Bean Intro- 

 duced. New Hampshire 4^51 lima 

 bean has now been named White 

 Mountain Bush. This variety is as 

 early as the earliest variety hitherto, 

 but its pods and seeds are as large 

 as late varieties and are produced on 

 low-growing, bushy plants. White 

 Mountain seems to have the ability 

 tc germinate in colder soil than most 

 lima bean varieties; hence, it should 

 be adapted to home gardeners in 

 New Hampshire and neighboring 

 states. It was selected from miscel- 

 laneous material sent by the U. S. 

 Department of Agriculture several 

 years ago.

Carnival Popcorn Attractive. For 

 a number of years we have been 

 working on a variegated popcorn 

 which produces kernals of many 

 colors, ranging from white and yel- 

 low through pink, purple, and black. 

 The variety has now been purified 

 for earliness, shapeliness of ear, and 

 for a reasonable degree of popping 

 quality. Because of its striking ap- 

 pearance, it has been named Carni- 

 val. It should have value, especially 

 for roadside marketing, as the ears 

 may be marketed for ornamental 

 purposes.
