TORONTO— -The detection of weed' seeds in lots of s»owing aeeds has been made'possibla by an instrument perfected by Dr D, H. Hamly of the Department of Botany at the 'University of Toronto, it has been announced by university officials.

"When viewed through the stereoscope, the photographs stand out in perspective, and the distinctive chaTacters of each seed, are made clear, even to a casual observer. One of the most important sources of loss to a farmer is in the weeds which grow in the crops he so'ws, according to nniversity officials, who believe that the instrument shonld help greatly in ridding the country of weeds. Already extensive work has been carried on to prove the worth of the. instrument, and should help greatly ridding the eonntry of weeds. Already extensive work has been received to allow some of the pictures to'be exhibited at the convention* of the International Association of Seed Analysts to be held in Europe this summer. " Material for Dr Hamly's photographs is obtained from the reference colleetion of seeds at the seed laboratory, university officials explained, it being the most complete seed colleetion in Canada, containing more than 13,000 different specimens, of which some 2000 were obtained last year by colleetion and exchange. The exchange list this year includes 217 institutions and individuals situated in 197 cities or 47 different countries.
