BOTANICON SINICUM. 81 
Wen hien t‘ung k‘ao, CCX VIII, 3, gives a short bibliographical 
notice with respect to this work. It is stated there that $3 2% 
Han O, the author, in compiling these Rules for Husbandry, 
made use of all preceding writings on the subject. 
The § # Nung shu is a treatise on husbandry in 8 books, 
written by pit Bi Ch‘en Fu, in 1149 A.D. The first part treats 
of Agriculture, the second of Breeding Cattle, the third of Rearing 
Silkworms. See Wylie’s Notes on Chin. Lit. p. 75. According 
to the Wen hien t‘ung k‘ao, CCXVIII, 6, the author was a 
hermit living in the Western mountains, about the middle of the 
12th century. 
Another work with the same title B% #¢ Wung shu,” in 22 
books, by 3 $§ Wang Cheng, was published during the Yiian 
period (18th or 14th century). This treats with great minuteness 
of the details of husbandry, and is illustrated by plates, each ac- 
companied by a stanza of poetry. The first six books, §% 3& ii Ht 
Nung sang t‘ung hie, consist of general rules for agriculture. 
This section is frequently quoted in the Kuang k‘iin fang pu and 
in later works on husbandry, as a separate work. It is followed 
by the a = Ku pu, on Cereals, 4 books, and then by a series of 
plates illustrating agricultural implements. See Wylie 1. c. p. 76. 
Wan Cheng also wrote two monographs on Textile plants, both 
illustrated by plates, viz.: 
The Fx # El ME Au mien tu pu, a treatise on the Cotton 
plant, and 
The jij 2 fy gi Ifa Ch‘u t‘u pu, on Hemp and Grass-cloth 
plants. ‘This is found reproduced in the Chi wu ming shi t‘u k‘ao, 
descr. part IX, 53. 
28 A third work with the same title appeared in the beginning of the Present 
dynasty. It was compiled by fe AMR WPF Chang Li siang. It is reprinted in the 
collection Chao tai ts‘ung shu (Wylie l. c. 137). | ee
