A VISIT TO DR SCHLICH'S FORESTS AT MIRWART. 245 



The estimated cost of this method of sowing is 10s. for the 

 seed and 32s. for the work, in all £2, 2s. per acre. 



Fosse Orban. 



Hex*e thinnings of undesirable trees had been made, and a light 

 crop, consisting principally of oak, remained ; this was to be 

 under-planted with spruce, the oaks being pruned up to a height 

 of about 1G feet. The shade was for the most part too heavy for 

 a crop of Scots pine, but this tree has since been sown on the 

 more open and drier portions of the area. 



Sapins de Biolin — 30 Acres. 



A crop of Scots pine, about twenty-four years old, raised by 

 broad-cast sowing. 



The first thinning had been made at the age of nineteen years, 

 when dead, injured, misshapen, and suppressed trees only were 

 taken. It realised about 4s. an acre net. A second thinning 

 had been made at the age of twenty-one years ) it was similar 

 in character, and realised about 16s. an acre net. A third 

 thinning had been made (at the age of twenty-four years). It 

 resembled the above, but a few additional stems were removed 

 from patches which appeared too dense. It realised <£2 an acre 

 net. The crop remaining after the third thinning consisted of 

 about eighteen hundred stems to the acre, or about half the 

 number that had been previously cut out. The height of the 

 dominant trees was 39 feet, their diameter being 5 inches at 

 i\ feet above the ground. Dead branches had been knocked off 

 up to a height of 8 feet. The ground was covered with moss, 

 unmixed with grass, indicating that the cover was not too open. 

 A fourth thinning, similar to the third, has since been made at 

 the age of twenty-seven years, and has realised £4 an acre net. 

 A fifth thinning will be made at the age of thirty years. It will 

 be somewhat heavier than those preceding it, in order to allow 

 the remaining trees to expand more rapidly in girth. It is 

 expected to yield £8 an acre net. The crop on the ground after 

 this thinning will be about six hundred trees to the acre. 



If it be then decided to clean-fell for pit-wood at the age of 

 forty years, and if it be evident that the desired diameter will 

 be attained at that age, the crop may be left alone ; but, if 

 necessary, a sixth thinning will be made between the thirty-sixth
