Why is there a 地 in (霉)旧地席的气味? From the second chapter in George Orwell's 1984, using the translations at Douban:


  Original: The hallway smelt of boiled cabbage and old rag mats.
  Translation 1: 门厅里有一股熬白菜和旧地席的气味
  Translation 2: 一进门厅就闻到煮卷心菜和霉旧地席的气味  


Question: Why is there a 地 in (霉)旧地席的气味?

It seems like it should be a 的, not a 地.  My understanding is that (霉)旧 (old) is an adjective describing the noun 席 (mat), and thus it should be 的.
「地」 is not a particle here. The word for rag mats is translated as the two-character word 「地席」, literally mat (席) for the floor (地).


  ...舊地席的气味
  
  ...smelt (气味) of (的) ... old (舊) rag mats (地席).
