The polarization of protons from the ${\mathrm{C}}^{12}(d, p){\mathrm{C}}^{13}$ reaction has been measured for a deuteron energy of 1060 kev at angles 20° and 140°. Elastic scattering by carbon was used to analyze the polarization. Nuclear emulsions were used as the proton detector. The observed magnitude of the polarization was found to be $P=54.3\mathrm{}\pm 9.5\%$ at 20° and $P=29.4\mathrm{}\pm 12.6\%$ at 140°. Positive sign of the polarization corresponds to the vector product ${\mathrm{K}}_p\times {\mathrm{K}}_d$.
