der side of the leaves, or flying from bush to bush. The 

 first young slugs hatch out usually about June 1st, and 

 increase in number during the month. These are of a 

 pale green color, ahnost transparent, and feed upon the 

 leaves, which soon look as if they had been burned. Dry 

 slaked lime scattered over the leaves while wet with dew 

 is a most convenient remedy that often proves effectual ; 

 but a more sure one may be had in frequently syringing 

 the plant with whale oil soap dissolved in water in the 

 proportion of one pound to eight gallons of water ; many 

 of the flies can also be destroyed with this solution if 

 applied when they first appear. The Eose Chafer, or 

 Rose-bug, is a troublesome insect, a small beetle, with 

 a slender body, tapering before and behind, measuring 

 near three-eighths of an inch in length, and covered with 

 ashen-yellow down. They usually appear towards the 

 middle of June, and remain from four to six weeks. 

 About the only way of destroying these is to pass over 

 the plants daily, shake or brush them into tin vessels 

 containing water upon which a little kerosene is floating, 

 or they may be gathered on sheets and burned. 



Mildew is a fungoid growth which shows itself upon 

 the leaves aud small twigs. It has a gray mould-like ap- 

 pearance, and seems to be invited by anything that causes 

 the growth of the plant to be suddenly checked. The 

 ordinary agent for destroying mildew is flowers of sulphur 

 dusted upon the leaves after wetting them, every few days, 

 until no more is seen. Rust frequently troubles Roses in 

 the garden, appearing on the leaves. Cut off and burn 

 the infected branches. 



SUMMER MULCHIXG. 



Borders containing Rhododendrons, Lilies, and other 

 plants that love coolness and moisture at the roots, 

 should early in the season receive a heavy mulch of 

 leaves, cut straw, bog-hay, or tanbark.
