following subjects:-—Remarks on the Viola tricolor; on the Genus 
Thunbergia, particularly of the Alata; on the Advantages of early 
Planting this Spring ; Culture of the Genus Pctpaver; Culture of the 
Hydrangea hortensis; Culture of the Trevirana coccinea and Mi - 
mulus cardinally; Culture of the Genus Macuna, or Cow-Itch; Cul¬ 
ture of Amaryllidece ; and Observations on Propagation by Cuttings: 
all which practical matter renders the number one of the most valuable
