We have made measurements of several Ds branching ratios, relative to the mode. We have observed two previously unseen two-body hadronic decays of the Ds+, namely and , and measured relative branching ratios of 2.860.38+0.36-0.38 and 3.440.62+0.44-0.46, respectively. We have determined the relative branching ratio for the decay into + to be 1.860.26+0.29-0.40. In addition, we have measured relative branching ratios for the + and + states, for which there had previously been conflicting measurements; our results are 0.54 0.09 0.06 and 1.20 0.15 0.11, respectively. Combining these new measurements with previous results and using (3.7 1.2)% for the value of B(Ds' +), we can account for (79 26)% of all Ds+ decays. In addition we have also measured relative branching ratios or set upper limits on D+ decays to all of the above-mentioned final states.
