A single plant sent from Indian Head bore more than one million and a half of needs. The seeds are very small, about half the size of timothy seeds, and conse(|uently are easily cleaned from grain ; they are of a reddish or greenish-brown color. The distribution of this plant is almost entirely by the wind blowing the stems across the prairie and over summer-fallow during the winter. This may, to a large extotit, be offset by using a woeder or drag-harrow after sowing, and thus destroying the young weeds or keeping them in check until the grain makes a start. During the summer all plants should be pulled from the edges of fields. Like other annuals this may be destroyed by summer-fallowing. Wild Mustard or Charlock. [Classed as a Noxious Weed.] This well known pest of Eastern Canada is spreading fast in the Territories. It is found wherever cultivation is carried on, and is quite plentiful in the older settled districts. Wherever settlers' effects have been unloaded at railway stations, plants may be found. This is a good illustration of the way in which weeds are introduced. Farmers will do well to use every effort to destroy every plant of it before it becomes more thoroughly established. This can he done by hand-pulling and the frequent use of the harrow and weeder on grain fields after the grain is above the ground. Closely resembl
