free from the leaf-spot, there was no marked difference between the 

 sprayed and the iinsprayed specimens. 



The experiments with spraying mixtures was continued in 1897, 

 and the record shows that "but very little blight upon the foliage 

 during the whole season, and no marked effect can be recorded for 

 the fungicides." The spraying continued through 1898, "but with- 

 out results, owing to the absence of the redbud blight." All this 

 time the plants had showed marked differences in hardiness. The 

 record for 1899 contains the following: "Two or three of the trees 

 were much injured during the last winter. Xo blight developed 

 during the summer, but several were somewhat injured by sun scald." 



This tenderness to the extremes of winter's frost and summer's sun 

 has been so great that at the present time the number of the healthy 

 plants is limited to three, while fully half have died and several are 

 unshapely and worthless as ornamental dwarf trees. One of the three 

 that has proved hardy is an especially fine specimen, and nearly per- 

 fection in its shape and luxuriant foliage. This plant flowers pro- 

 fusely in early spring and fruits abundantly in autumn. Seeds are 

 gathered from this, and it is hoped that, by careful selection from its 

 seedlings, a hardiness may be obtained, after a few generations, that 

 will place this redbud among our most attractive lawn trees.

EXPERIMENTS WITH LAW^N GRASSES. 



The nine plots seeded to grasses, as shown in the following table, 

 iiave been kept cut with the lawn-mower during each season since 

 1896. The condition, or stand, of each kind of grass is given in per- 

 centage, following the jilot number and kind of seed sown :
