NATURAL HISTORY, TORONTO REGION
four pounds, but they were exceptional ; from one and a half to two being about the average size of the spring run of Suckers.
Common Mullet. Red-horse. Moxostoma aureolum (Lesueur).—This is the handsomest and best of all the Sucker family. It was formerly an abundant spring visitor to the Humber and Don Rivers, but owing to persistent netting during the spawning sea-son it is now very seldom seen. In the early spring, as soon as the ice moves out, Mullet run up the streams to spawn, forcing their way through the swiftest torrents in order to reach the gravelly beds, upon which the ova are deposited. After spawning they retire to deep water. While in the streams they will readily take worm bait, and as they frequently attain a weight of four or five pounds they afford good sport in the waters they frequent.
CYPRINIDAE. (The Carps.)
Creek Chub. Horned Dace. Semotilus atromaculatus (Mitchill).—This species sometimes attains a length of twelve inches ; it is very abundant and generally distributed in all the streams of this vicinity. As a food fish it does not take high rank, though it affords a great deal of sport for rural school-boys. It spawns in early summer on the stony shallows in the streams it frequents.
Red-sided Shiner. Leuciscus elongatus (Kirtland).—This beautiful little fish is found in most of the streams having a muddy bottom.
