Also no reference seems to be made of the 

 ancient irrigating ditch that now skirts the 

 blufEs east of the Jemez Eiver, some twenty- 

 five feet above the present ditch. Also no 

 mention has ever been made of the petroglyphs 

 on " red rock " in the valley about a mile 

 north of the present village of Jemez. Here 

 are drawings of deer, lightnings, snakes, the 

 sun and moon, Montezuma and the footprints 

 of " the great road-runner."

THE BERKELEY ASTRONOMICAL DEPARTMENT 



To THE Editor of Science: It has recently 

 come to the attention of the Berkeley astro- 

 nomical department of the University of Cali- 

 fornia that Dr. See's reference to it (p. 479 

 of the issue of Science of Oct. 8, 1909) has 

 created an erroneous impression concerning 

 the connection of the department with his re- 

 cent theories of cosmogony. This note is to 

 point out that the Berkeley astronomical de- 

 partment has, in no way, either approved or 

 disapproved them. Its attitude has been en- 

 tirely neutral, as is evidenced by several news- 

 paper interviews, in which it has always been 

 definitely stated that the department would 

 te in no position either to affirm or to refute 

 any of Dr. See's theories until the completed 

 work becomes available. This completed work 

 lias not yet appeared. 



It is to be added that from June, 1908 until 

 August, 1909, Professor Leuschner, director 



of the students' observatory of this depart- 

 ment, was abroad on leave and that the writer, 

 as acting director, is entirely responsible for 

 all matters emanating from here during that 

 interval.

SCIENTIFIC BOOKS 

 Foundations of American Grape Culture. By 



T. V. MuNSON, D.Sc. Denison, Texas, T. 



V. Munson & Son. 1909. 



The colossal work of Dr. Hedrick and as- 

 sociates of the Geneva (N. Y.) Agricultural 

 Experiment Station (already reviewed in 

 Science)' has been of inestimable service in 

 furnishing a ready means of identification of 

 grape varieties under cultivation, by means of 

 superb colored illustrations and detailed de- 

 scriptive matter. That volume is mainly de- 

 voted to results of tests and observations at 

 the station on a very wide range of cultivated 

 varieties, and does not assume to discuss bo- 

 tanical relations or the subject of interbreed- 

 ing, except as standards of reference. 



Those who have for many years watched the 

 determined, painstaking labors of Dr. Mun- 

 son, in Texas, have anticipated pleasure and 

 profit from the monument he was expected to 

 erect in the form of a book recording the out- 

 come of his patient work and great sacrifices 

 to compass the production of advanced types 

 of grapes in the arduous process of breeding 

 for quality. 



" Foundations of American Grape Culture " 

 comes as a veritable boon to many who owe its 

 author much for previous aid and encourage- 

 ment in the tedious and unremunerative 

 practise of grape breeding. It is so filled with 

 meat, so well and compactly arranged and 

 thoroughly indexed, so copiously illustrated 

 with most excellent reproductions from life, 

 and so thoroughly digested, that it is im- 

 possible to characterize its contents in a sen- 

 tence. The volume is remarkable in breadth 

 of scope, completeness of treatment and 

 wealth of detail, yet in clearness, conciseness
