Stems ending in s and x" present peculiar forms when the accent 

 falls upon the semivocalic y and w, into which these sounds are trans- 

 formed. The y becomes e, the w becomes o. Thus we have from — 



x'is- to disappear x'e'^nakula to disappear grad- 



ually 



q.'Els- to sink under water qlsle'lc^ sunk into water V 



488.9 



^rriEns- to measure ^mEne'lc^ measured V 477.1 



tiETns- to beat time t.'Eme'dzd to beat time on a 



flat thing III 86.5 



sex^- to paddle sid'^rmkula to paddle along III 



297.10 



yix^- to dance yu'^ndJcula to dance along 



In some cases the preceding vowel, if accented, is contracted with 

 the y which has originated from s. 



qas- to walk qd'^nakula to walk along 



qd'nodze^ to walk alongside of 



The use of dz and y in place of s does not seem to follow any definite 

 rules. Thus we find— 



lE'ndzEVfi (la-ns-Em) means of ^mE'nyETn {^rriEns-Em) meas- 



taking under water X 62.10 uring instrument 



qd'dzas place of walking (con- 

 sidered not as goods as 

 qd'yas) 



gwd'yAxsta (gwds-Exsta) to hd'dzEXstax'Hd (hds-Exsta- 



bring mouth near to one III x'Hd) to begin to make noise 



71.33 III 161.22 



^wd'layas (^wdlas-as) size X Jia^ne'dzas (han-es-as) canoe 



161.25 lying on beach X 161.17 



A purely phonetic change belonging to this class is the palataliza- 

 tion of Z:" and jc" preceding an o or u. q.'dk^- slave becomes qld'Tc'o; 



^mslc^- A ROUND THING BEING IN A POSITION beCOmCS ^mEli'd'la ROUND 



THING ON WATER (island) ; psx'^- TO FLOAT becomcs fEX'd'la to 



FLOAT ON WATER. 



(.5) Ilecij)roeal Changes 



These are partly purely phonetic, partly etymological. Contact of 

 consonants results in their adaptation to admissible combinations. 

 Therefore terminal Tc and l surds are changed before initial conso- 

 nants of suffixes into their spirants. This change is also made when, 

 in a sequence of two words which stand in close syntactic relation,
