the mnple^ the poplar^ the elm^ the falloiv, the 

 alder y the jilberd and hafel are among the firfl 

 that put out leaves ; the plane tree alfo is very 

 early. Nat. Hid. lib. 16. 25. 



The foliation or leafing of the firfl four 

 named trees, i, 2, 3, 4, varies very much as to 

 the time, and the day on which they break 

 bud •, for as the winter goes off fooner or later, 

 fo they are in leaf fooner or later. But this 

 does not hold of the reft, e. g. in the year i750> 

 in which there was fcarcely any winter- weather, 

 but the whole was almoft a perpetual fpring, i 

 obferved towards "the latter end of March, that 

 the currant and goofeherry were in blow about 

 Gripenberg \ whereas the lafl year they did not 

 blow till the middle of April. The oak^ and 

 the ajh feldom fhew their leaves before the night 

 frofls are over"". For which reafon gardeners 

 do not venture to truil their houfe plants to 

 the open air, till the leaves of the laft trees give 

 (ign of a mild winter. 



» This agrees with lord Bacon's obfervations, Nat. Hifl:. p. 

 146. that a long winter makes the earlier and later flowers 

 come together. This i oblerved was the cafe in the year 

 1755, ^hen tne fprmg was very backward. The author 

 fays in a note, that it has been obferved for above ten years 

 paft, that the oak has been always in leaf before the end of 

 May, in Upland.
