Culture during the rest period. Com- 

 mencing with the training when young. 

 They are best in single stems of about 

 two feet in height; and the head should 

 "branch off equally, to accomplish which, 

 some pruning back is requisite during 

 the first year or two, whilst the head is 

 forming, and the latter should be kept 

 thin in the centre. When the trees are 

 well established an annual pruning should 

 be resorted to, consisting of still keeping 

 the centre of the bush somewhat open, 

 and in thinning out any cross shoots and 

 superfluous spray. It must be observed, 

 that the fruit is produced on shoots of 

 the preceding year, and generally on 

 portions which have been well exposed 

 to the light. Any coarse or robust 

 shoots should be shortened back nearly 

 half their length ; these will frequently 

 produce axillary branches of a fruit- 

 ful character. Do not prune until the 

 blossoms are showing; this will be 

 about the beginning of February. The 

 female blossom is like a minute brush, 

 of a pinkish colour; the male is the 

 well-known catkin. In pruning, much 

 regard must be paid to these blossoms, 

 especially the female ; scarcely a twig 

 may be cut away containing them. This 

 makes it evident that most of the prun- 

 ing, or rather, thinning, requisite should 

 have been well carried out prior to the 

 commencement of fruitfulness. 



It often happens that filbert-trees will 

 possess female blossoms with few or no 

 male catkins. When such is the case 

 there will be no crop, unless means be 

 taken to bring the male farina within 

 their reach. Catkins must be sought 

 about the period when the male dust is 

 just beginning to burst. Branches con- 

 taining these may be tied here and there 

 amongst the bushes most needing them. 

 It matters not what kind of nut they are 

 from ; probably the wild hazel is best. 



Fruit : how to keep. When gathered, 

 the fruit must be kept in jars, in a cool 

 cellar, with husks on. If it is desired to 

 impart a fine, fresh-looking colour to the 

 husks, they must be placed in a close 

 vessel, and a small pan of sulphur gently 

 burned, or rather, smouldered, beneath 

 them.

 APHIS COBYLZ. 



CORYMBS, a spike of flowers, the flower 

 stalks of which are longer in proportion 

 us they stand lower down the main stalk 



supporting them, so that the flowers are 

 with a top nearly level. Those of Spira'a 

 opulifo'lia and of the Mountain Ash sue 

 examples.
