Fig. 1. Habitat of nest No. 22, July 10, 1926, in a deserted but 
subdivided vegetable garden at Pie Til. e dominating 
weed is charlock (Brassica arvense). Beside a clumb of this, in 
the center ground, the nest was placed. 
- 2. Nest No. 22, July 8, 1926. On all sides but the southeast 
coe lres (Brassica arvense) rises. When the nest was con- 
structed, some three weeks earlier, the habitat was undoubtedly 
less weed-grown, more in keeping with Lark requirements.
