Spruce and Silver Fir f inch, Acorns about 1J inches, 

 Chestnut 2 inches, Beech f inch, Maple and Ash \ inch, 

 while such seed as Birch, Cupressus, or Thuja giyantea, 

 should only be given the slightest covering. (A slight 

 allowance for subsidence of the soil is made in the depth 

 of Acorns and Chestnuts.) 



Another method of making the drills is to use a roller 

 with raised ridges upon its surface, which press into the 

 soil when the roller is drawn along the bed. A local 

 blacksmith will make hoops of iron that can be nailed or 

 screwed on to a wooden roller at the widths required. 



The seed may be sown in the lines either by hand or by 

 means of the sowing horn, a contrivance much used in 

 Germany for sowing conifer seeds. It is fitted with five 

 nozzles of different sizes to regulate the quantity sown. 



A light machine drill made by the Planet, Junr., firm 

 can be used for sowing seed, but the objection to this is 

 that the man using it must walk on the beds, which should 

 be avoided. 



(3) Sowing in Lines across the Bed. 



To make the drills across the bed a wooden roller may 

 again be used, but with the bars running from side to side 

 instead of encircling the roller. These can be made of 

 wood to the width and thickness required to make a drill 

 deep enough for the size of seed to be sown. Another 

 contrivance that is being used more now in England is 

 the Bavarian drill-board. It consists of a board about 

 an inch thick, that has been well seasoned so as not to be 

 liable to warp, with projecting pieces of wood running
