TREATISE OH 



About tlie middle of March, fow the firft, fecond, and thh'd 

 forts on beds, in a lliady well-jQieltered border, but much thinner 

 than the Pines, as they are to remain two years. 



The three remaining forts do not rife by a fortnight at leaft 

 fo foon as thefe do ; and as they make very Httle progrefs the firft 

 year, all art and induftry fiiould be ufed to promote their growth 

 as much as poffible, otherways many of them will be fpew'd out 

 of the ground, and the weaker plants entirely killed, if the fol- 

 lowing winter is fevere,. The befl fecurity, therefore, againft all 

 thefe common accidents being to fow early, let them be fown a 

 a fortnight fooner than the three preceding kinds, that is, by the 

 beginning of March, the weather permitting. The ground for 

 the feeds of thefe plants cannot be too rich a natural foil, or too 

 finely prepared ; it mufc alfo be loofe and dry, which, if not of 

 that quality originally, mull be rendered fo, by mixing it with 

 fand,, and elevating the beds fix or feven inches above the alleys, 

 to draw away the moifture. 



The Balm of Gilead, and Hemlock Spruce, are a little tenderer 

 at firft than the other forts, and will be much aided in their 

 growth, if the beds are hoop'd over, and covered with mats for 

 five or fix weeks after the plants appear above ground, both in 

 the middle of the day when the fun is warm, and at night 

 when the air is cold or frofty ; and, during that time, they will 

 require a gentle watering every fecond evening when it does not 

 rain. 



At lowing all the kinds of Firs, negledl not to clap over the 

 beds with the back of a fpade. This makes the furface fmooth 

 and level, prevents the feeds from being iiTegularly fcattered in
