8 
OF ROOT 
THE “CARTER” METHOD 
SELECTION. 
RCOOTEREO TRADE MARK. 
The “ Carter ” Method comprises a combination of tests by ascertaining^— 
1. The specific oravity of the entire root as a ”uide to its keeping 
quality. 
2. The specific gravity of the juice as a guide to its feeding quality. 
3. The percentage of sugar and its allied compounds. 
4. 1 he total amount of dry matter. 
The principles upon which the “Carter” Method of Selection is based can be 
succinctly stated as follows : — 
1. All roots have a tendency to contain an excess 
of water, which excess is quite valueless. 
2. A small deviation in the percentage of water 
alters materially the feeding value of a crop. 
3. 'I’he obvious necessity arises of ascertaining the 
weight of solids in any Root Crop. 
4. Food values and the digestibility or otherwise 
of the solids can be determined by analysis. 
5. Fiixamination of Roots and valuation of Root 
Crops on analytical principles bring to light their 
true and only value for food. 
6. The “Carter” method is to analy.se each Root 
planted for seed purposes, and to reject all which 
do not reveal a strong combination of the above- 
mentioned (jualities. 
7. Roots which stand this crucial test provide for 
the next year a hardier race and more generous food 
producers. 
8. This selection on analytical principles is a 
combination hitherto unknown and untried by any 
other seed house.
