Outline for Selective Breeding of Timothy 



First Year. 1. Manner of procuring seed from starting a selec- 

 tion. When timothy is ripening, go over a field and choose a 

 number of good ripe seed-heads from tall, robust culms which 

 appear to come from good plants. Also look for exceptionally 

 good plants from along the roadsides and fences, and whenever 

 they are found, preserve good heads for seed. Choose good seed- 

 heads from at least 10 or 12 of these good plants. Thresh the 

 seed from these heads, keeping the seeds from each plant sepa- 

 rate, and sow them immediately. No time should be lost. 



2. Planting the seed. The seed should be planted early in 

 August. Take small boxes about 2 feet long by 1 feet wide 

 and 4 inches deep ; fill them with good soil from some locality 

 where there has been no timothy and thus where there is little 

 likelihood of timothy seed being in the soil. Pack the soil down 

 slightly in the box and smooth off the top, removing all lumps. 

 Plant the seed in the boxes in short rows, placing the rows about 

 2 to 2f inches apart. In planting the seed open shallow furrows 

 in the soil and sow the seed by hand, arranging so that the seed 

 will be only very lightly covered. Sow the seed as thinly as 

 possible in the rows and thin out later so that the plants will
