there for many years, and there was extremely little organic matter 

 present ; moreover, lime and the necessary mineral foods were present in 

 sufficient quantity. It would seem to fulfil the conditions mentioned on 

 p. 10 of Professor Bottomley's " Seed and Soil Inoculation," under which 

 inoculation is stated to be necessary. 



No manures were used in connection with the trial. 



On each type of soil four rows of each variety were sown, each row 

 being 21 feet long, and in every case a row sown with inoculated seed 

 alternated with a row sown with untreated seed. Thus at the end of the 

 experiment the weights of produce from two rows inoculated and two rows 

 uninoculated of each variety were obtained. The varieties of peas employed 

 were Carter's 1 Eight Weeks,' 1 Early Morn,' and 1 Yorkshire Hero.' The 

 culture fluid was prepared in the laboratory with all care to prevent 

 unnecessary contamination and precisely according to the directions given. 

 The temperature was regulated correctly, and the liquid used for the 

 inoculation of the seed as soon as it appeared sufficiently cloudy. The 

 inoculation was performed by immersing each lot of seed, contained in 

 a small muslin bag, into the liquid until thoroughly wet. The seed was 

 then spread out in a cool shady place until quite dry and then planted, 

 the same amount of seed being used for planting each row. 



At about the time of flowering plants here and there were taken up 

 from corresponding rows, and their roots examined with regard to the 

 formation of nodules. Apparently throughout, nodules were formed quite 

 as abundantly on the uninoculated plants as on those inoculated. No 

 differences were observable at any period between corresponding rows on 

 the same ground, whether with regard to general growth or to the time of 

 coming to maturity. 



The following tables give the results obtained, showing the total 

 weight of pods from each row expressed in grams. (The rows of 1 Eight 

 Weeks' peas on the good soil were neglected, as just before picking they 

 were somewhat damaged by pigeons) : —
