is described where a border of zinnias was cat down to the ground 

 after being badly affected by frost on May 20. The plants grew again 

 and flowered, but the colour of the blooms was entirely altered in some 

 cases. A white variety striped with red bore some quite red flowers; 

 a purple-striped variety became plain purple, and plain-coloured 

 varieties turned from red to white, etc. In some cases also there were 

 curious modifications in the form and structure of the flowers; such 

 alterations, as in other well-known cases, being clearly due to the 

 modification of nourishment following on the suppression of the stem 

 of certain shoots through the action of frost and through their removal 

 at a certain stage of growth. — M. L. H. 



Zoologry, Agricultural. By H. A. Gossard {U.S.A. Exp. 

 Stn. Ohio, Bull 198, pp. 15-88; with 9 plates; Nov. 1908).— This 

 is a short, thorough, and very clear account of all the most im- 

 portant friends and enemies of the American farmer and gardener 

 among beasts, birds, and insects. In every case a remedy or means 

 of prevention is described, and in a clear, plainly written fashion, 

 which should be understood by any intelligent farmer. General pro- 

 grammes are given for the treatment of various special crops, and a 

 monthly calendar showing what insect pests are likely to appear 

 and what should be done. Altogether a most valuable and practical 

 publication, at least for those who live in Ohio. — G. F. S.-E.
