Sycamores Ihould not be fown thick ; if they 

 rife an inch apart, it is abundantly thick for one- 

 year feedlings : and if intended for two-year feed- 

 lings, they fhould not rife nearer one another 

 than two inches. 



Sowing Birch and Alder. 



This is now a proper time for fowing Birch 

 and Alder feeds. We have feveral times had oc- 

 calion to notice the quality of foil moil fuitable 

 for thefe kinds. The land, however, mould ei- 

 ther have been under a preparing green crop, or 

 fallow, the preceding feafon, and previoufly dung- 

 ed, that the manure may be well incorporated 

 with the foil previous to fowing. 



The land muft be carefully digged, and parti- 

 cularly broken, from top to bottom, in the dig- 

 ging. The raking alfo muft be performed with 

 great attention to part the foil very fine. It is 

 hardly pollible to cover Birch feeds too little, if 

 they be covered at all. The covering therefore 

 muft be very gentle. It need hardly be obferved, 

 that a calru day mould be chofen for fowing 

 birch feeds, as for all others that are light. 



The preparation for Alder feeds is the fame 

 as for the Birch: The covering, however, for 

 the former ought to be a quarter of an inch thick j 

 aad the bed form for both kinds is the beft. A!-
