We use data collected by the CLEO III detector at the Cornell Electron Storage Ring to measure the inclusive yields of D{sub s} mesons as B({upsilon}(5S){yields}D{sub s}X)=(44.7{+-}4.2{+-}9.9)% and B({upsilon}(4S){yields}D{sub s}X)=(18.1{+-}0.5{+-}2.8)%. From these measurements, we make a model dependent estimate of the ratio of B{sub s}{sup (*)}B{sub s}{sup (*)} to the total bb quark pair production of (16.0{+-}2.6{+-}5.8)% at the {upsilon}(5S) energy.
