Observations were made on the density of naturally and artifically formed lake and river ice. The effect of initial snow density, size and shape of snow crystals, rate of water spread and rate of freezing on the density of snow- ice obtained was studied in the laboratory and is presented in graphical form. The observations indicate that snow-ice formed under natural conditions will probably have a density between 0.85 and 0.90 g./cm.(3). The classification of snow- ice obtained was studied in the laboratory and is presented in graphical form. The observations indicate that snow-ice is discussed briefly. On a effectué des observations de la densité de glace de rivière et de glace de lac formées naturellement et artificiellement. La densité de la neige, les dimensions et la forme de ses cristaux, la vitesse de pénétration de l'eau et sa congélation ont un effet sur la densité de la glace obtenue en saturant la neige d'eau; cet effet a été étudié en laboratoire et est présenté sous forme de graphiques. Les observations montrent que la densité de cette espèce de glace, obtenue dans des conditions normales, oscille probablement entre 0,85 et 0,90 g/cm(3). La classification de cette glace est discutée brièvement. Peer reviewed: Yes NRC publication: Yes
