The past season was a fine one for grass and all the plots did 

 better than the previous year but the mixing in of other than 

 the original species sown makes it difficult to change the figures 

 and, therefore, they remain as for 1903. It would be necessary 

 to let the grasses grow up to flowering condition to determine 

 how far each species is responsible for the turf that is in each 

 plot. 



Experiments With Weeds. 



The weed belt has been continued for eight years without 

 the soil or its productions being interfered in any way. The 

 following table shows the leading fourteen species for the past 

 season. Those of the list that have been among the first four- 

 teen in previous years have their rank shown under the year in 

 which they were recorded :

It is seen that four of the species that were in the first list 

 ^1897) are still among the first fourteen, and it is to be observed 

 that the ragweed holds nearly the same rank this season as it 

 did eight years before. It has been first on the list for two years, 

 and in 1901 it was the last to get a record. It is also to be noted 

 that a rank growing aster came in two years ago, and has gone 

 rapidly to the first place. The sorrel, velvetleaf and wild carrot 

 hold nearly the same place they did seven or eight years ago, 

 while the grapevine this year has become so large and strong as
