at night. We commence covering with a single mat 

 at the beginning of December, and in severe weather 

 add a Uttle refuse straw or hay, so as to admit of giv- 

 ing the structure air, to allow the escape of any super- 

 fluous vapour, and to maintain a healthy sturdiness of 

 growth.] 



We fear we have been rather too copious in our 

 observations ; so various, however, are the structures 

 employed to grow pines, that it is a difficult matter 

 so to write as not to mislead. ♦ 



We will conclude this section with a few remarks 

 on the harvesting of soils, as it is aptly termed by 

 Mr. Barnes, and which might have been inserted on 

 the same page with his remarks. We consider a dry 

 March the most eligible period : a winter's frost will

 and weeds the more the better — will be in a fine 

 mellow state in about six to nine months ; if it lays
