WILLOW. 289 



a Calendar of Mora, made in Sweden during the year 1755, 

 thus notes : 



March XIX. Mowers of the round-leaved or eared sallow open on the 

 19th of March, the thawing-month, which commences from 

 the first melting of the snow to the floating of ice down the 

 rivers. 



Eaves of houses drop towards the noontide sun. 

 XX. Snow melts against walls. 



Larks begin to sing. 

 XXII. Water flows by the walls. 

 XXV. Roads very dirty and full of water. 



The same naturalist has inserted in his calendar, that 

 when the willow, concerning which we speak, begins to 

 leaf, migratory birds return in Sweden to their accustomed 

 haunts. 



April IV. Upright fir-moss sheds its dust. 



Stones are loosened from the ice. 

 VI. Hills begin to appear, the snow being melted. 

 Serpents come out of their holes. 

 Water-spiders frisk about ; the fly creeps forth. 

 Black game and lapwing reappear.
