Pissarro and Cézanne leave L'Union, the group started by Pissarro and Alfred Meyer.

After Pissarro participates in a second auction with poor results, Murer, in an attempt to help Pissarro and Sisley, organizes a lottery.

Pissarro works with Cézanne at Pontoise.

During the latter part of the 1870s, Pissarro's comma-like brushstrokes frequently record the sparkling scintillation of light, as in Orchard with Flowering Fruit Trees, Springtime, Pontoise (1877).

Forms do not dissolve but remain firm, and colors are strong, as in Red Roofs (1877).
