An extremely rare alpine prostrate little under-

 winter covering of snow in its native climate. 

 Seeds or division of the plant ; peat and loam ; a 

 dry situation on a bank in summer, and a dry 

 corner in a cold pit in winter.

1. Au- 



DIBBER, or DIBBLE. This 



J instrument for making holes 



V //in which to insert seeds or 



plants is usually very simple 

 in its construction, being at 

 the best the head of an old 

 spade - handle. To secure 

 uniformity of depth in plant- 

 ing beans, &c., by this in- 

 strument, it is useful to have 

 it perforated with holes to re- 

 ceive an iron peg, at two and three 

 inches from the point, as in 

 the annexed outline. It 

 should be shod with iron; 

 for if this be kept bright it 

 will make holes into which 

 the soil will not crumble from 

 the sides. The crumbling 

 is induced by the soil's ad- 

 hesion to the dibble. For 

 planting potatoes, a dibble 

 with a head three inches in 

 diameter at the point, eight 

 inches long up to the foot- 

 rest, and with a handle four 

 feet long, is to be preferred. 

 For the insertion of seed, a 

 dibble that delivers the seed 

 has been invented by a Mr. 

 Smith, and another by Dr. 

 Newington ; the last is the best.
