We present a preliminary measurement of the angular clustering of faint ($R \le 25$) field galaxies in which we concentrate on the behavior of $w(\theta)$ on small angular scales ($\theta \ls 10''$). The galaxies are strongly clustered and $w(\theta)$ is well-characterized by a power law of the form $A_w \theta^{-\delta}$. The best-fitting value of the power law index, $\delta$, is, however, steeper than the fiducial value of $\delta = 0.8$, indicating there are more pairs of galaxies separated by $\theta \ls 10''$ in our sample than would be otherwise expected. Using the best-fitting form of $w(\theta)$, we estimate that $\sim 10%$ of the galaxies are in physically close pairs (separations $\ls 21 h^{-1}$ kpc). This is a factor of order 2 larger than local galaxy samples, but comparable to galaxy samples with $
