Mr. Editor - The following memoranda of the crop of grapes in a cold house, with a span roof, may be interesting to your correspondent, H. B., and other cultivators of the vine. The season here is about a fortnight later than at Staten-Island.

1842, August 16, Pitmastons ripe. Sept. 4, Black- Hamsburghs, ripe.

1843, Jane 1, Tines in bloom. August 15, cut two bunches.

17, " ten " 18 and 20,.out thirteen bunches. 26 end 27, " thirty-three. 15 to September 5, two hundred and forty Sept. 5 to Oct. 7, six or seven hundred. After Oct. 7, six or seven hundred - the whole crop being fifteen hundred rind thirty-six bunches', on'one hundred viner planted out in 1840, in outside border. The following hints may be useful to those who are their own architects and gardeners:

1. Build with as much-glasr, and as little material thai will condense moisture, as pos sible.

2. Place houscreest' and west; end glawf ends as well as roof, and 1st it be exposed on alt sides to sun and light.

As thirlast direction differs from some opinions expressed in the Horticulturist, I give the following reasons for it: I found'a house so placed to answer perfectly well, and not to hare any inconvenience from too much heat on the South, or too little on the north side. In some seasons, all the light and heat that can be obtained, is not too much to ripen the wood thoroughly; and although Ido not know that a house running north and south will not answer perfectly Well, yet I bare some doubt-whether the wood and fruit buds Will ripen as perfectly every year, as in one running east and west.
