FOREST-TREES. 121 



above the regard of common expence, and want to promote their 

 growth as faft as poffible, a readier practice may be followed, 

 and which, for three or four years, will make the plants double 

 the iize of thofe raifed in the natural way. 



. For this purpofe, the beginning of March, fow the feeds thin 

 in penny-pots, and plunge them to the rim in a moderate hot- 

 bed of tanners bark, rather than horfe-dung ; the heat of the 

 bark being more equal, lading, and lefs fteam arifing from it, 

 than that of the dung. When the feeds have been a week fown, 

 they muft be very gently watered every third or fourth day j 

 after the plants come above ground, every fecond day, and the 

 quantity of water increafed as they advance in growth. When 

 the plants are about five or fix inches high, which may be about 

 the beginning of May, draw out the ftrongeft of them, leaving 

 the fmal'ler in the fituation they were in ; plant each of thofe in 

 a leparate penny-pot, and plunge them again into another mo- 

 derate hot-bed, watering them frequently and plentifully, co- 

 vering the glalfes with mats when the fun fliines in the heat of 

 the day, to prevent their being fcorched, and admitting a 

 proper quantity of air to them, that they be not over-drawn. In 

 this condition they may remain till about the firft of Auguft, 

 ■when the bark will have loft moft of its heat, and when the pots 

 may be taken out of it, but ftill kept in the frame, though more 

 and more expofed to the open air daily, till the glafTes are taken 

 away wholly during the mild weather of the autimm months. 

 On the approach of winter, the glafTes muft again be replaced on 

 their frames, to prote6l the plants in fevere ftorms only ; but 

 they ought to be fully expofed to the open air, when the feafoji 

 is temperate.
