 Later Bulthuis is translated Don Quixote from Spanish and wrote another youth novel.The most extensive commentary on Bulthuis's works is by Nekrasov, who wrote extensive critiques of both his original novels from a Marxist viewpoint for the ante-schism ""La Nova epoko"" (The New Epoch) (Oct. 1929-Feb. 1930) and for the post-schism ""La Nova Etapo"" (The New Stage) (1932).That was too tendentiously Marxist to encounter general agreement.
