These seeds possess some nutritive value as a feed for stock, but are a very undesirable addition to a crop. This weed does much damage, particularly in Alberta and Saskatchewan, by robbing the soil of raois- ture and food, which would otherwiee be increasing the yield of good marketable grain. The great mistake made in summer-fallowing for the destruction of Wild Buckwheat is, that the work is not as a rule commenced until the plants have attained considerable size and seeds are forming. Plants are left protruding between the furrows and readily ripen seed. In a dry season partly filled seeds would ripen under ground sufficiently to sprout. Surface cultivation immediately after harvesting would in some seasons induce the seeds covered to grow and the young plants would be killed by frost. In any case, they will make an early start in spring and be killed by cultivation either for crop or summer-fallow. If a crop is sown on infested land, a drill should be used and the ground harrowed frequently until the grain is several inches high. Lamb's Quarters, Pigweed, Fat-Hen. Although this native plant is not included in the list of noxious weeds, there is no doubt that it is responsible for much loss to the farmers, as it is present to a greater or less extent in almost every grain field in the country. This is clearly indicated by an examination of the screenings at the elevators. Often underestimated as an enemy, on account of its common occurrence, it is given the freedom of the farm. It is hardly necessary to describe this tall weed, with its mealy green leaves, often used as a pot-herb. Being an annual it read
