3T4 Learned Societies 



7. The Agricultural Society long ago recommended the 

 white hawthorn, buckthorn, barberry, hazel, crab-apple 

 snd willow for quickfet hedges ; but as all thefe are not pro- 

 per for the fame foil, and as there is great want of quickfet 

 hedges in the ftoney, fandy diftricls expofed to the wind, be- 

 caufe people are not acquainted with the kinds of trees that 

 can be ufed, or with the method of planting them, though 

 we poffefs indigenous as well as foreign trees of the bum 

 kind, which in this refpecl: have been either tried in fome 

 places or may be recommended, the Society requires to know 

 which of the tree or bufli kind, confidering the different foils- 

 and diftricls of Denmark, can be employed with the greateft 

 advantage for quickfet hedges, and what is the beft method 

 of planting them ? 



The author muft give, along with the common and beft 

 known kinds, the Danifli fyilematic names; thofe leaftknown 

 he mull briefly defcribe, and in fuch a manner as to be un- 

 derftood by farmers. In both cafes he muft give all the 

 Danifli trivial names, and the Linnean fyilematic appella- 

 tion of each kind, with a reference to the figure in the Flora 

 Danlca, if it be there reprel'ented. The obfervations on 

 the utility of each kind of wood for quickfet hedges, and the 

 xnethod of planting it, together with the determination of 

 the foil which it requires, muft reft upon the grounds of cer- 

 tain experience. 



Each of the papers on thefe fubjefts will be rewarded by 

 the Society, in proportion to its novelty and the importance 

 of the obfervations it contains, with 100 dollars ; but the 

 beft and fulleft, when more than one are tranfmitted, with 

 '3.00 dollars.
