mination period is not a good measure for the seed value; also 

 that slow seed is undesirable. 



The reviewer would add, since the germination tests upon which 

 these conclusions are based were merely commercial tests, under- 

 taken with no special consideration of the scientific use to be made 

 of them, and are, moreover, relatively few, the conclusions should 

 be accepted with caution by the practice, the preceding article brief 

 claiming equal attention.

In an article of over 30 pages, Hauch de- 

 Block scribes in great detail his experiences with 



Planting. the planting and management of beech and 



oak in Denmark. The most interesting 

 part is an account of a novel method of planting beech, the so- 

 called Bregentved (named from Hauch's district), or block plant- 

 ing, which is suggestive. 



It was introduced some 14 years ago — hence results are visible 

 — to overcome the failure of natural regeneration and sowing or 

 ordinary planting on the cold stiff loam soil, undrained and al- 

 most undrainable on account of absence of any fall, the most un- 

 promising field on which every measure had failed, not only with 

 beech and oak but with other species. 



The peculiarity of the beech that it requires a thoroughly dense 

 stand in its youth to succeed — such as a natural regeneration if 

 successful shows, about 800,000 to the acre — suggested the need 

 of planting in mass, by which at least 80,000 plants in clumps 

 without too great cost could be set out. 



The plant material is grown in nurseries of rich soil to secure 

 a compact root system, sowing in the spring, the ground having 

 been prepared to a depth of 16 inches in the fall. The beech 

 nuts, properly wintered, are sown in furrows or rills made with 

 a special rake of 6 inch width, 6 inch apart, four furrows to the 

 long bed, with 12 inch walks between beds. The nuts are evenly 

 distributed in the rills at the rate of 140 bushels to the acre and 

 covered not quite an inch by using a rake for drawing the soil over 

 them. The next spring the plant material is ready to be put into 

 the field. Instead of taking up the single plants, whole blocks, 6
