vermin than when they are covered with straw or hay. 

 They are usually covered up about the middle of Decem- 

 ber, and are not uncovered or otherwise disturbed until 

 the first of May, when they are lifted up and tied to the 

 wires, and started as before described. In cases where 

 it is not practicable to cover with sand or soil, the vines 

 can be laid down snugly along the front wall and covered 

 up with mats or bagging ; but in either manner of cover- 

 ing up the grapery must be freely ventilated during the 

 warm part of the day, unless in extremely cold weather. 



VARIETIES. 



The varieties that I consider to be best suited for a cold

 Hamburg, 1 Royal Ascot.

 1 Buckland Sweetwater, 2 Muscat of Alexandria, 2 Can-

 even at lowest rates seem to give a good deal of money 

 for their weight, the surplus is thus thrown upon the 

 market, bringing down the price below what is a paying 

 rate to the regular grower. 



I regret the necessity of being compelled to compress
