Tliis is a third gen- eration plant from Sand lucerne. commences either immediately below, or a short dis- tance below, the base of the crown, and the various branches at first grow out in a lateral direc- tion, but later take a more vertical downward into tihe soil. Comparisons were made between the stems and foliage of the plants having the different root sys- tems, and the superioritv of having branalied roots as compared with the single tap-root was very striking, being usually much more vigorous and liealthy in growth, and consequently yielding a mnclh heavier crop. This examinntion. fliougli it was reararded as being only of a preliminai-\- natui-e yet was sufficient to furnish convincing evidence that in any attempt to improve the of Alfalfa, the character of the â¢â oot system should be considered to be of primarA- importance. One of the greatest advantages to a plant having a branched root over the single tap-root is the mudh firmer anchorage it gives to the plant; thus enabling it to resist far more effectuallv anv tendency to be heaved out of the .soil by winter frosts and .spring thaws. " ⢠It is a fact well-known to Alfalfa growers that one of the most common causes of failure to retain a p"ood stand is not so T'lueh flie low temperatures ex- nevieneed durinsr winter as alternate freezing ^ind thawing which mav oi'"ur in tlie snrin". The .Alfalfa is heaved out and the roots exposed i" such a wav that a comnarativelv 'iffht fi-ost is sufficient to destrov th" maioritv of the plants. It is under such « that plants witli the branched rpn+s are seen to great advantage. This was clearlv demonstrated in t
