Sept. 1 The Hot-House 443 



bark-bed -is weak, once in a week will be fufficient; 

 efpecially after the middle of this month. 



Adding frejh Tan. 



About th**, latter end of this month youfhould procure 

 a proper quantity of freih tan from the tan yards to be 

 ready to renew the bark-beds in the hot-hoiife and ftove 

 the next month. 



For this purpofe you fliould provide as much new tan 

 as will be equal to one half at leaft of what the bark-pit 

 will contain, though fonietimes two thirds or more is re- 

 quired ; according as the old bark is more or lefs walled. 



When the tan is brought in, let it be thrown up into 

 a heap, and let it lie for ten or twelve days to drain 

 before it is put into the hot-houfe. 



But if it is very wet, as is fometimes the cafe when 

 newly throv/n out of the tan-pit, it^ihould, provided the 

 weather be dry, be fpread abroad thinly where the fun 

 comes', to lie two or three days, that the fun and air 

 may draw off or exhale the grofiePc of the moiilure ; for 

 if put in too wet, it will be a long time before it will 

 acquire a proper degree of heat. 



The tan or bark for the above purpofe fliould be fuch 

 as hath been about a fortnight or three weeks, or at moit 

 a month out of the tan-pit; and alfo obferving, that as 

 fome of the tan is pretty large, and fome quite fmall, 

 the middle- fizcd bark is what fhould be chofen. 



For the future management, fee the work of next 

 month. 



Cro'vjns and Suckers of Pine Plants. 



The bed wherein this year's crowns and fuckers are 

 plunged fhould be kept to a good heat, by which means 

 the young plants will make good roots before winter. 

 ■ if they are in a good bark-bed, the heat will not yet 

 want ^ny augmentation ; but if the pots were placed 

 iipon a dung hot-bed, let a lining of frefh hot dung 

 be applied to the fides of the bed, when you iind th3 

 heat is decreafed ; obfn-ving to raife the lining about 

 tvvo or three inches higher than the bottom of the frame. 



And about the latter end of this- month it wHbbe pro- 

 per to lay fome hay or ilraw round the outfides of the 

 frame, v/hich v/ili keep out the froft,.and preferve a 

 kindly growing heat in the bed.
