THE PI- AY. 

 Nora. — The uodorliafj caril wini trick, ftiij card below it leads next. 

 A Y B 7. KEMARK.S AND INFERENCES. 



1. A loads our old friond tlio 

 singleton. The score being at 4, 

 lie liopcs tr) get a trick or two by 

 nifting, nnd to secure the odd 

 trick nnd the game. Y, from his 

 own hand, and from his familiarity 

 with A'a way (who, liowever, apart 

 from )iis weakness for a singleton 

 lead, is a strong player) knows that 

 A has not led fi-oni strength, be 

 therefore, though with only three 

 trumps, 



2. Leads a trump. B probably 

 holds 10 and a small one (A being 

 presumably weak in trumps). 



3. The finesse here is perfectly 

 sound. Z has returned the C of 

 .Spades, 8 being the trump card, 

 therefore he held four originally. 

 It is very unlikely that B holds 

 Queen. With Queen, 10, 9, and 

 small one, ho would not have 

 played 9 to trick 2. 



5. Having cleared out trumps, 

 except his partner's turn-np card, 

 i' proceeds with his long suit. 



7, 8, 9, and 10, B's discards are 

 bad. .4, having discarded Hearts, 

 can bo strong only in Clubs (for 

 there has been no such overwhelm- 

 ing trump strength against A and B 

 as to justify A in discarding from 

 his best suit). B therefore should 

 have retained his Hearts ; he cer- 

 tainly should not have unguarded 

 his King. It would have made no 

 difference so far as game was con- 

 cerned ; but as it is, Y Z make 

 ei-i'nj tricl;. Had A originally led 

 Ace of Clubs, Y Z would have 

 made no more than the odd trick.

 sound ; try again.

 Maxwell, \V. F., G. T. Brown, 

 li. C. T., Jack, A. J. K., G. Brown, 

 correct ; Molequo not quite correct. 

 Several correspondents consider 

 Editor in Chief's objection just j 

 but it is not. The problem is quite 

 sound. — Five of Cubs.

D. O'P. Miloy.— With such limi- 

 tations, the intermediate call seems 

 worth adopting. (.Vfter all, there 

 are similar limitations in the case 

 I'f nearly all signuls.) — Five of 



CLtlLS. 



Moj^il consider* the hand in No. 22 an unsatisfartorj- illustration 

 of the wonknciS of load fnm short suit ; and that the tricks woold 

 have been iilentieal, though played in u didorcnt order. Thisscenu 

 to me on incurred view. If A had indicated bis strength in tmmpa, 

 H, though he could not have returned trumps, would have led a 

 heart after lii-i dianionils were established. As the game wu 

 actually played, B had nothing to show that at trick he sbonld 

 have led a heart. f)f course, if ho had done no. the game would 

 have lieen saved (as Mogid points out) in spite of A'n bad leod. — 

 Five ok Cutis. 



IIdw NiT.ME<iS Grow. — Nutmegs grow on little trees which look 

 like pear trees, and are generally not over twenty feet high. The 

 flowers are very much like the lily-of-tho valley. They are pale, and 

 very fragrant. Tlio nutmeg is the seed of the fruit, and mace is 

 the thin covering over the seed. The fruit is about as large as a 

 peach. When ripe it breaks 0|)en and shows a little nut in.iidc. 

 The trees grow on the islands of Asia and tropical America. They 

 bear fruit for seventy or eighty years, having rii>e fruit upon tlicm 

 all the seasons. A lino tree in Jamaica has over •1,00l» nutmegs on 

 it every year. The Dutch used to have all this nutmeg trade, as 

 they owned the Banda Islands, and conquered all the other traders, 

 and dest royed the trees. To keep the price up, they once burned 

 three jiilcs of nutmegs, each of which was as big as a church. 

 Nature did not sj-mpathise with such meanness. Hie nutmeg 

 pigeon, found in all the Indian islands, did for the world what the 

 ])utch had determined should not be done — carried those nuts, 

 which are their food, into all the surrounding countries, and trees 

 grew again, and the world had the benefit.
