Apargia autumnalis and a few Dandelions (L. Taraxicum). 

 The country was more open and less planted hereabouts. We 

 slept at Enghien ; and in walking in the park and garden the 

 next morning, I saw nothing in blow but a few roses and 

 marigolds. The leaves were turned yellow and falling, and 

 in a much more autumnal state than in France and England. 



5th. Gentle showers, with fair intervals. The country 

 became more wooded again with Ashes and Beeches in rows 

 as we passed through Halle to Bruxelles. The atmosphere 

 is certainly more transparent than in the Eastern part of 

 England : we saw the lofty spires of the Hotel de Ville of 

 Bruxelles, and other high buildings, at a great distance. 



The Aster Chinensis, A. Tradescanti, and Marigolds, are 

 most cultivated, and are now in blow in Belgium. The 

 Aspen Trees and Poplars are less common here than in 

 French Flanders. The rows are seldom composed for long 

 together of Lombardy Poplars, though I saw some of pro- 

 digious growth, considering they were first introduced into this 

 side the Alps only about sixty years ago. The limes are not 

 so fine as in Kent, Sussex, and Surry.

 point of view, being by the side of a canal made for the 

 treckschuyts and barges. The marsh groundsel was the only 

 flower I saw.
