### Abstract

Weak coupling perturbative calculations of the Wilson loop in lattice gauge theory are carried out numerically up to order g^{4}. Comparison of the results with those of the Monte Carlo calculations shows that there exists a non-perturbative contribution of an essential singularity type which may be identified as the string tension.
