40 CORN. [1900 



brought under notice, I give the following short notes contributed by 

 various correspondents. 



In 1881, Mr. B. Brown, of Deard's End, near Stevenage, wrote 

 regarding a maggot infestation which appeared to be similar to that 

 under consideration, that it attacked some portion of his Wheat there, 

 sown after dead fallow, and its ravages were so great that he discon- 

 tinued planting Wheat after fallow. The Wheat looked well until 

 after Christmas, but began to die oft' in the spring mouths. In 1882 

 Mr. W. Creese, writing from Teddington, near Tewkesbury, regarding 

 this attack (of which specimens had then been trustworthily identified), 

 observed that it attacked plants on land that had been fallowed in the 

 previous summer, but did not appear on land ploughed for the first 

 time in the autumn ; also that it leaves a belt of four or five yards 

 near the ah/e untouched. And in a report given me by Mr. Parlour, 

 of Middle Farm, Dalton-on-Tees, near Darlington, in 1888, he men- 

 tioned, "I have examined several fields in the district, and find that 

 almost all fallow field s have suffered more or less. In no case, so far as I 

 can find out, has any Wheat been attacked where the land was cropped 

 last summer," 



The special reports of 1888 and 1889 mention the attack as being 

 most commonly observed after fallow, and after Turnips or Swedes, or 

 where a portion of these have failed, or sometimes after Potatoes where 

 they have been raised before they are ripe, or raised early, or had thin 

 amount of leafage. 



The only precise report of loss in an infested crop consequently on 

 presence of the Wheat-bulb Maggot which I am aware of having been 

 circulated, was sent me by Mr. Michael Ellison, of Barber Woodhouse, 

 on Dec. 27th, 1889, and I re-insert it, as drawing attention with exact- 

 ness to the great amount of loss in the Wheat crop that these small 

 maggots are able to cause. Mr. Ellison, after some remarks on our 

 previous cqrrespondence regarding H. coarctata, observed : — 



" It may interest you to know the result of the cropping and yield 

 which I have just lately learned from the tenant. From one field of 

 eight and a half acres there was no ' first ' corn ; only three loads or 

 nine bushels per acre of ' seconds.' The other field of twelve acres 

 yielded sixteen sacks of four bushels each of ' firsts,' and of ' seconds ' 

 same as above, three loads per acre." — (M. E.) 



In the following notes of observation of attack in three localities 

 during the past season, it will be noticed that one is mentioned as 

 being after fallow, and one after Potatoes. 



The first report of presence of the maggot in 1900 was sent me by 

 favour of the editor of 'The North British Agriculturist' on May 2nd, 

 and appeared in that journal, with my reply, on May 9th. The 

 inquirer communicated under the signature of "Forfarshire"; but I
