loss of good seed is involved. With this 

 process the division on specific gravity 

 basis is accurat'C and the loss of good seed 

 is reduced to the minimum. Some of the 

 lots of alsike seed were cleaned from Re- 

 jected to No. 1 with less than 4 per cent 

 loss. The loss is usually well under 10 

 per cent unless the seed contains an ex- 

 ceptionally large proportion of other 

 kinds of cultivated seed, dirt, chaff, etc.. 

 as well as weed seeds. 



Color and Vitality. 



Clovi?r seed treated is greatly improved 

 in color and general appearance by eli- 

 minating timothy seed, brown dead clover 

 seed and small particles of dust and dirt 

 adhering to the seed. 



Germination tests have been made of 

 several lots before and after cleaning and 

 the results show somewhat higher germina- 

 tion with the cleaned seed. This is prob- 

 ably due in part to a certain percentage of 

 the' dead seed being removed, and in part 

 to some of the seeds which were previously 

 impermeable to moisture being made germ- 

 inable by the process. 



The color of samples of clover and 

 timothy seeds- which were treated a year 

 or more ago is maintained as well as or 

 better than that of the untreated seed. 



More Seed Can Be Grown Profitably. 



From the results noted above it will 

 be evident that a large proportion of the 

 clover seed produced and marketed can 

 be made much cleaner and its commercial 

 value greatly increased by the new clean- 

 ing process. A large quantity of low 

 grade seed which with previous methods 

 of cleaning, could not be made saleable, can 

 now be put into good marketable condi- 

 tion. Several of the lots treated were 

 practically unmarketable as received after 

 being cleaned by ordinary methods, and 

 were converted into good marketable seed 

 by our process. A nujnbei- of lots of screen- 

 ings containing from 25 per cent to 50 

 per cent weed seeds were handled. From 

 this material which was practically worth- 

 less the gocd seed was reclaimed jiiui i)ut 

 into marketable condition. 



The process makes it possible to utilize 

 to good advantage a much larger propor- 

 tion of the seed crop produced, and also 

 to grow clover seed profitably on land 

 infested with certain weeds, the seeds 



of which previously could not be removed 

 from clover seeds. This applies to parts 

 of Ontario where Ragweed, False Flax, 

 Canada Thistle or Mustard have rendered 

 clover seed growing unprofitable and to 

 Western Canada where Russian Thistle, 

 Stinkweed and Mustard have defeated 

 several attempts to grow alfalfa and clover 

 seed. 



Timothy. 



Timothy seed has been very successfully 

 treated with the object of making a separ- 

 ation of the hulled and unhulled seeds. The 

 original stock graded No. 2 on account of 

 hulled seed and the separations graded 

 Extra No. 1 (unhuUed) and No. 3 (hulled). 

 Alsike and other clover se?.d was com- 

 pletely removed from the unhulled portion 

 of the timothy. Results wnth small samples 

 indicate that the prooess will be valuable 

 in removing certain weed seeds from tim- 

 othy. 



Seed Grain 



The work with grain thus far has been 

 limited to a few small lots but re.sults in- 

 dicate the probability of valuable separa- 

 tions being made, such a,s oats and barlej' 

 from wheat, barley from oats, peas con- 

 taining weevils from sound peas, and cer- 

 tain Aveed seeds from grain. By regulating 

 the density of the liquid used any desired 

 proportion of a sample of grain can be re- 

 moved which makes possible accurate 

 selection of seed on specific gravity basis. 

 This may be of value in plant breeding 

 work for developing heavy-weighing 

 strains of grain. 



CHANTECLER FOAVL 



Breed Recognized by Americjui Poultry 

 Association. 



T.ne Chant ecler, the only purelv Can- 

 adian breed of fowl, originated by Brother 

 Wilfrid at the Oka Agricultural College, 

 is now a standard variety. The secretary 

 <tf the Chanteclei- Breeders' Association in 

 Ottawa received word from Seattle, w-hero 

 the annual meeting of the American Poul- 

 1 1 y Association was recently in session, 

 that the breed had been admitted to the 

 AnxM-ican standard of perfection.
