teristics, little difference due to treatment has been noted. Twenty-five-year- 

 old Northern Spy apple trees, unfertilized but mulched with hay, continue to 

 produce much better than those grown in sod only and fertilized. The aver- 

 age increased production over a period of years has been six bushels per tree 

 per year. 



Trials to determine the extent of bruises and injuries to Mcintosh ap- 

 ples from picking were made under similar conditions, using canvas picking 

 bags and metal-sided, open-bottom type of bucket. Data taken at the termi- 

 nation of the storage period on fifteen 100-apple samples gave 44.5 bruises 

 of one-half inch or less in diameter, and 2.3 bruises over one-half inch in dia- 

 meter, per 100 apples when picked into canvas bags. Apples picked into 

 metal-sided buckets showed 37.5 and 3.3 bruises, respectively, per 100 ap- 

 ples.

ORNAMENTALS 



Chrysanthemum Variety Tests 



In a variety test of hardy chrysanthemums consisting of 138 varieties 

 which were not protected by mulching during the winter, the following were 

 rated in the spring of 1947 as fully hardy: Sundance, Little Eskimo, Bambi, 

 Igloo, William Longland, White Knight, Pipestone, Aviator, White Gold, 

 Morning Star, Welcome, Snowball, and two unnamed white seedlings of the 

 University of New Hampshire designated as H-1-45 and H-6-45. Varieties 

 listed as second degree hardiness (that is, which survived well enough to make 

 good sprouts) : Glowing Coals, Thala, Courageous, Rose Spoon, Red Riding- 

 hood, Primula, Yellow Spoon, Flash, Red Gold, Bonfire, Eggshell, Stewart, 

 Dean Ladd, Harmony, and R. C. Cummings. The other 109 varieties killed 

 out completely during the winter. Through an oversight, the named New 

 Hampshire introductions were not given a comparable test this year.

Lilac Culture 



The lilac arboretum, which was badly infested with oyster-shell scale, 

 was cleared up satisfactorily by the use of Elgetol while in a dormant con- 

 dition. New lilac seedlings of late-blooming types began blooming in 1947 

 from plants grown from seed in 1945. A plant resulting from a cross made 

 by Henry Clapp between Syringa japonica and Syringa vulgaris is making 

 satisfactory growth but as yet has produced no blossoms.

PASTURES 



Producing the Full Roughage Requirements on New Hampshire 

 Dairy Farms with Special Reference to Pastures 



It is the purpose of this project to determine which of the tall grasses is 

 best suited for seeding with ladino and whether or not any of the newer ones 

 are superior to timothy, the most common grass.
