58 JOURNAL OF THE ARNOLD ARBORETUM [vol. iv. 



which he bases his conclusion) — 6b are loose, of a different paper and 

 smaller page, seeming to prove that they were taken from some other copy, 

 and ff. 6a-6b are plainly manuscript (a few leaves at the end are also 

 wanting). Hain's date of 1484 seems the safest for us to accept. 



Columella was born probably at Cadiz, (Gades) and wrote in the 

 first half of the first century. He was the author of the most important 

 Latin work on ancient agriculture, "De re rustica" in twelve books of 

 which "De cultu hortorum" forming the tenth, not the eleventh as given 

 in the title, is in verse. That "Liber xi," is a typographical error is 

 evident from comparison with copies of " De re rustica" in the Arboretum 

 library. 



Both the "Ortuli" and the "De cultu hortorum," are extremely rare. 

 The latter is, according to Brunet, "Editio princeps;" it is by an un- 

 known Italian printer "D. S." (by whom it is signed) and is not known in 

 any of the French libraries. 



Other incunabula in the library are given in the following list, each 

 entry giving reference to Hain's "Repertorium bibliographicum," with fre- 

 quent reference to Dr. Arnold Klebs' "Incunabula lists, 1." To Mr. 

 George P. Winship, librarian of the Widener Collection at Harvard Uni- 

 versity, I am also indebted for help in identifying some of our copies.
