made from any of the strains they should retain the original num- 

 ber and be given a second selection number as well. Thus, if selec- 

 tions are made from strain 25 they should be designated as 25-1, 

 25-2, 25-3, etc. If several varieties are used, either the name of the 

 variety should be used with the selection, or the variety should be 

 designated by a number which precedes the selection number. Thus, 

 we may have Silvermine 1, Silvermine 2, etc., or 1-1, 1-2, etc. In 

 this latter case the first figure of each couple designates the number 

 of the variety, and the second figure the selections of that variety. 

 Selections of variety No. 2 would be numbered 2-1, 2-2, etc. The 

 sample page from a notebook shown below, which can be made by 

 (ruling vertical columns on ruled paper, illustrates the system of 

 numbering and the essential notes which should be taken each sea- 

 son on all the selections. These notes should be kept in a permanent 

 cover, such as the loose-leaf binders which are usually obtainable at 

 stationary stores. 



Record of Oat Selections for 1908. 



As shown in the above table the rows of the plat are numbered 

 consecutively, with every tenth row as a check. Selection 114 and 

 three selections from it were planted, 1, 3, and 5. This indicates 

 that selections 2 and 4, and selections of this strain bearing higher 

 numbers than 5, have been discarded in previous years. Of strain 

 115 we have two selections, 1 and 4, and a reselection of 4, recorded 

 as 115-4-1. No further selections have been made of strains 118 and 

 119. The selections which have the numbers 116 and 117 have been 

 discarded. 



All dates are recorded by figures representing the month and 

 day of the month. Thus, the date of planting was 4-3, or April 

 (the fourth month) 3. Resistance to rust is recorded as the per- 

 centage of freedom from this disease. Resistance to lodging and 

 shattering are entered in like manner. Selection No. 114-1, which 

 lodge very little, is marked 98 per cent resistant, while 114-3, in 

 which there is considerable lodging, is given only 80 per cent. The 

 yield is recorded as ounces of thrashed grain to the row. Quality
