A study of charm fragmentation into Ds*+ and Ds+ in e+e- annihilations at √s=10.5 GeV is presented. This study using 4.72±0.05 fb-1 of CLEO II data reports measurements of the cross sections σ(Ds*+) and σ(Ds+) in momentum regions above x=0.44, where x is the Ds momentum divided by the maximum kinematically allowed Ds momentum. The Ds vector to vector plus pseudoscalar production ratio is measured to be PV(x(Ds+)>0.44)=0.44±0.04.
